Previously, it drew a line from 3,0 to 1,5 to 2,10 , resulting in overlapping areas. If you want to draw filled polygons, consider using the fill function instead.
The datastore and tabularTextDatastore functions detect and return date and time data as datetime type. Previously, datastore and tabularTextDatastore functions returned date and time data as character vectors. For details, see Read Remote Data. Import Tool: Import strings and categorical arrays interactively. The import tool now supports importing text as string and categorical data types.
For more information, see Import Tool. Previously, the Import Tool imported text data as a cell array of character vectors. To preserve that behavior, change settings in the Text Options field in the Imported Data section of the Import tab. Control and customize how data is imported from fixed-width text files using the detectImportOptions function and creating a FixedWidthImportOptions object. Use the FixedWidthImportOptions object with readtable to customize import options, such as:.
Import only a subset of data using the SelectedVariableNames property. For more information, see FixedWidthImportOptions. Previously, the save command, when saving workspace variables to a MAT-file, used compression as the default and the only option. Now, a new option, '-nocompression' , allows saving of data without compression.
This option is only available to use with MAT-File version 7. By default, saving a variable myVariable to a MAT-file in version 7. To save myVariable without compression, use: save -v7. Now, you can specify a character encoding of your choice by using the 'Encoding' parameter.
It previously used version. For nonnumeric arrays, this function converts a JSON null value to an empty double array []. This behavior affects the webread and webwrite functions when processing JSON content. Previously, jsondecode decoded a JSON null value as an empty double array, which is dropped from the output. To preserve the old behavior in the jsondecode function, that is, to remove the NaN values from the resulting numeric array, use the rmmissing function:.
Both the load and fopen functions take filename as an input argument. When specifying this filename , use the file separator character preceding a file name to indicate that the file is in the root folder.
If myFile. That is, the load function returns an error, and the fopen function returns a -1 indicating that the file could not be opened, because no such file exists in the root folder.
If no such file was found in the root folder, then MATLAB would attempt to find and return the file from the current folder. However, now, if you add a file separator preceding the file name, then the load and fopen functions will only look for the file in the root folder.
To indicate that file is located in current folder use load 'myFile. Then, on UNIX platforms:. Reading video files, with old file formats, on macOS platforms using VideoReader. The macOS platform no longer supports certain older video file formats. To read such files using VideoReader :. Open the video file using the QuickTime player. If the file is supported on macOS, the player automatically converts the file into a newer format. Use VideoReader to read this new converted video file.
Now to index tall arrays, you can use ascending or descending sorted indices. The indices can specify elements anywhere in the array, and allow for duplicates. Convert a tall table containing a time variable into a tall timetable to facilitate calculations on large sets of time-stamped data. To find outliers in your data, use the isoutlier function. To replace outliers with alternative values, use the filloutliers function. Smoothing noisy data is now possible with the smoothdata function. For example, smoothdata A,'movmedian' smooths data with a moving-window median.
To return a structure that contains a summary of a table or a timetable, use the summary function. Also, you can bin the data using units of time as the bin edges, such as 'second' , 'hour' , or 'week'.
Use a sliding window to compute the moving median absolute deviation and the moving product along data in an array with the movmad and movprod functions. Find the smallest and largest elements of an array with the bounds function. Filling missing data using a moving mean or moving median option is now available with the fillmissing function. Moving Statistics Functions: Supply sample points for time-stamped and nonuniform data in moving statistics functions, such as movmean. Providing sample points that represent the location of data in an array is now possible when computing moving statistics with the functions movmad , movmax , movmean , movmedian , movmin , movprod , movstd , movsum , and movvar.
For example, you can compute the moving-window average of data in an array A with respect to times in a vector t using movmean A,'SamplePoints',t.
Now you can exclude NaN s when calculating the product and cumulative product of an array with the prod and cumprod functions. Normalization option of histcounts and histcounts2. The Normalization option of histcounts and histcounts2 now computes the normalization using the total number of input data elements.
App Designer: Learn to build apps using an interactive tutorial. Learn how to build a simple app using an interactive tutorial that guides you through each step in the process. You can access this tutorial in the App Designer Open menu.
Enable zooming and panning for plots in your apps using the zoom and pan functions. To enable this functionality, add buttons to your app that call zoom and pan in their callbacks.
For more information, see Graphics Support in App Designer. App Designer: Configure columns of a table to automatically fill the entire width of the table. MATLAB automatically calculates column widths so that they expand to fill all available space within the width of the table. This behavior is enabled by default, or whenever the ColumnWidth property of the Table UI component is set to 'auto' for one or more columns. App Designer: Manage common design-time settings using the Preferences dialog box.
Specify which options are always enabled or disabled whenever you work in App Designer. For more information, see App Designer Preferences. App Designer: Include comet , graph , and digraph visualizations in apps. Use comet to display comet plots, and use the graph plot function to display graph and digraph plots. Create apps containing interactive plots by writing ButtonDownFcn callbacks for graphics objects such as Line or Bar objects.
For example, here is a ButtonDownFcn callback saved as mybuttondown. App Designer: Edit table column headings directly in the canvas. Now you can edit table column headings directly in the canvas.
The Uitable Properties panel automatically reflects your changes. SizeChangedFcn callbacks no longer execute when the automatic resize behavior is enabled. The automatic resize behavior is enabled when the Resize components when app is resized check box in the UI Figure Properties panel Design View is checked. In previous releases, the presence of a SizeChangedFcn callback disabled the automatic resize behavior.
Now, the automatic resize behavior must be disabled to allow the SizeChangedFcn to execute. Apps created in previous releases will not execute the SizeChangedFcn callback if the automatic resize behavior is enabled.
Open your app in App Designer, and select Design View. For more information on these methods, see Property Set Methods. You can improve performance on some storage devices by saving variables to MAT-File version 7. Memoization is an optimization technique used to speed up programs by storing the results of expensive function calls and returning the cached result when the program is called with the same inputs.
For more information, see memoize. Scripts: Improved performance of scripts with lower script overhead. MATLAB has improved the performance of invoking scripts, especially when invoking a script from another script. The time savings becomes more noticeable as the number of components in your app increases. Mathematics Functions: Various performance improvements. Arduino : Read from quadrature encoders. Class matlab. OnOffSwitchState: Represent on and off as logical values.
The matlab. Class definitions for properties enable you to specify size, class, and other criteria that MATLAB uses to validate values assigned to properties. For more information, see Validate Property Values. Validation Functions: Validate that values meet specific criteria by calling the appropriate function.
Validation functions determine if values meet specific criteria and return descriptive error messages if the values do not satisfy these criteria. The primary use for validation functions is for property validation. For more information on using validation functions, see Property Validation Functions. A has no NaN and no Inf elements. A has no NaN elements. A is an exact match for a member of B. Mocking Framework: Isolate a portion of a system to test by imitating behavior of dependent components.
When unit testing, you are often interested in testing a portion of a complete system isolated from dependent components. To imitate behavior of dependent components, use the mocking framework. For more information, see Mocking Framework. To record screenshots and save figures, pass ScreenshotDiagnostic and FigureDiagnostic instances to test qualifications or the log method of the TestCase class.
For example, within a test, testCase. To produce the artifacts independently from qualification failures, use the TestCase. For more information, see matlab. The DiagnosticResult property name has changed to DiagnosticText in the following classes in the matlab.
QualificationEventData class have been removed. The properties they replace were cell arrays of character vectors. The DiagnosticResult property in the matlab.
LoggedDiagnosticEventData class has been removed. It is replaced by the DiagnosticResults property that contains DiagnosticResult objects. The DiagnosticResult property was a cell arrays of character vectors. If your tests generate screenshots and figures during tests, they are included in a test report generated with the TestReportPlugin class. However, you can indicate that your test report includes passing diagnostics, or explicitly log the artifacts in your test using the TestCase.
To pause test execution and enter debug mode in the event of a test failure, use the 'Debug' option. To run tests at different verbosity levels, use the 'Verbosity' option.
For more information, see runtests. Unit Testing Framework: Select tests by procedure name. You can run tests with a specified procedure name. The procedure name is different from the test element name because it does not include any class or package name or information about parameterization. In a class-based test, the procedure name is the name of the test method. In a function-based test, it is the name of the local function that contains the test. In a script-based test, it is a name generated from the test section title.
To select and run test elements with a specified procedure name, use the 'ProcedureName' name-value pair with the runtests , runperf , and testsuite functions or the TestSuite suite creation methods.
To select test elements from an existing test suite, use the TestSuite. You can use the TableComparator class with the IsEqualTo constraint to compare table values recursively. Prior to Ra, they used the ObjectComparator , which is less strict. Therefore, it is possible that if you have tests that compare classes, test that used to pass might now fail. To create a table of summary statistics from the results for running a measurement experiment on a test suite, use the sampleSummary method of the MeasurementResult class.
Performance Testing Framework: Apply a function across test measurements with the samplefun method. To apply a function across the Samples of a MeasurementResult array, use the samplefun method.
Pull fetches the latest changes and merges them into your current branch. Previously, you had to fetch and merge separately before you could see changes. You can run existing binary MEX files without rebuilding. For more information, see Version Compatibility. If you build MEX files without using the mex command options -largeArrayDims or -compatibleArrayDims , then review the table in Compatibility Considerations to avoid depending on default behavior that changes in Ra.
This table shows the changes you must make to your mex command to build existing MEX files or S-functions. Or: mex myMex. MEX files and shared libraries: Diagnostic information displayed for failure to load.

Python : Supports string data type. For more information about string data types, see Characters and Strings. For more information, see Pass Data to Python. The string function converts py. For more information, see Handle Data Returned from Python. The functions pyversion and pyargs accept the string data type for input arguments. For example, for the py. Python Version 3. To ensure continued support for your applications, upgrade to a supported version of Python—version 3.
To ensure continued support for building your MEX files, consider upgrading to another supported compiler. For an up-to-date list of supported compilers, see Supported and Compatible Compilers. Negation of matlab. Change the logic for tests that rely on the negating the ReturnsTrue constraint.
Generating test suites from a class that derives from a concrete base class that defines methods that reference a TestParameter , MethodSetupParameter , or ClassSetupParameter not defined within the base class. Base class as Abstract using the class-level Abstract attribute. Abstract parameter properties for all parameters used by methods of the class.
For example, properties Abstract,TestParameter. In future releases, if your test class inherits from a concrete base class that uses a parameter that is not defined in the base class, MATLAB will throw an error. Changes to fieldnames causes the syntax obj. Use the fieldnames function with objects of type COM and Java.
Defining a property get method for a constant property is not supported. Constant properties do not support the use of a get method because the value does not change by design.
In future releases, defining a property get method for a constant property will result in an error.
