Functions and System Objects in DSP System Toolbox that Support C Code Generation
If you have a MATLAB® Coder™ license, you can generate C and C++ code from MATLAB code that contains DSP System Toolbox™ functions and System objects. For an example, see Generate C Code from MATLAB Code. For usage rules and limitations while generating code from System objects, see System Objects in MATLAB Code Generation (MATLAB Coder).
You can view functions and System objects that are supported for C/C++ code generation in documentation by filtering the functions reference list. Click Functions right below the blue bar at the top of the Help window, then select the C/C++ Code Generation check box at the bottom of the left column under Extended Capability. The functions and objects are listed in their respective categories. You can use the table of contents in the left column to navigate between the categories. Refer to the Extended Capabilities > C/C++ Code Generation section of each function page for any usage notes and limitations.
