    Add the %#codegen pragma to a function to prompt the MATLAB Code Analyzer to identify warnings and errors specific to code generation.

    function y = my_fcn(x) %#codegen
....

    Tips

    • You do not need to add the %#codegen pragma to functions in a MATLAB Function (Simulink) block. The Code Analyzer always reports warnings and errors specific to code generation for code in a MATLAB Function block.

    • For a list of the checks performed by the Code Analyzer when you add the %#codegen pragma, see MATLAB for Code Generation Messages.
