Stateflow.exportAsClass

Export MATLAB class for standalone chart

Since R2019b

Syntax

Stateflow.exportAsClass(source)

Stateflow.exportAsClass(source,destination)

Description

Stateflow.exportAsClass(source) saves a standalone Stateflow^® chart as a MATLAB^® class file in the current folder. The saved file has the same name as the chart. For example, if source is chart.sfx, the function saves the MATLAB class in the file chart.m.

Stateflow.exportAsClass(source,destination) saves the chart as a MATLAB class file in the folder destination.

Note

The MATLAB class produced by Stateflow.exportAsClass is intended for debugging purposes only, and not for production use or manual modification. For more information, see Tips.

Examples

Export Chart in Current Folder

Save Stateflow chart chart.sfx as the MATLAB class file chart.m in the current folder.

Stateflow.exportAsClass("chart.sfx");

Export Chart in Folder Specified by Path

Save Stateflow chart chart.sfx, which is located in folder dir1, as the MATLAB class file chart.m in the current folder.

Stateflow.exportAsClass(fullfile("dir1","chart.sfx"));

Export Chart to MATLAB Class in Another Folder

Save Stateflow chart chart.sfx, which is located in the current folder, as the MATLAB class file chart.m in the folder dir2.

Stateflow.exportAsClass("chart.sfx","dir2");

Input Arguments

source — Path and file name of standalone Stateflow chart

string scalar | character vector

Path and file name of a standalone chart, specified as a string scalar or character vector. You can use the absolute path from the root folder or the relative path from the current folder. Standalone charts have the extension .sfx.

Data Types: char | string

destination — Path of destination folder for MATLAB class file

string scalar | character vector

Path of the destination folder for the MATLAB class file, specified as a string scalar or character vector. You can use the absolute path from the root folder or the relative path from the current folder. If not specified, the function saves the MATLAB script file in the current folder.

Data Types: char | string

Tips

• Use the code produced by Stateflow.exportAsClass to debug run-time errors that are otherwise difficult to diagnose. For example, suppose that you encounter an error while executing a Stateflow chart that controls a MATLAB application. If you export the chart as a MATLAB class file, you can replace the chart with the class in your application and diagnose the error by using the MATLAB debugger.

  Note

  Error messages produced by the MATLAB class point to different line numbers than the corresponding error messages produced by the Stateflow chart.

• When you execute the MATLAB class produced by Stateflow.exportAsClass, the Stateflow Editor does not animate the original chart.
