There are special considerations when you create MATLAB® functions that are intended for code generation. These include certain
restrictions when you use
varargout, recursive functions, anonymous functions, and
nested functions. To generate code for MATLAB recursive functions, the code generator uses either compile-time
recursion or run-time recursion. To produce efficient C/C++ code, the code generator
sometimes creates multiple versions of a function, referred to as function
specializations. In certain cases, you can prevent the code generator from creating
function specializations by using
coder.ignoreSize. While generating a MEX function, you can bypass
code generation for a specific function in your MATLAB code and instead use the MATLAB engine to execute the call. To do this, use the
|Declare a function as extrinsic and execute it in MATLAB|
|Prevent use of constant value of expression for function specializations|
|Prevent code generator from creating function specializations for constant-size expressions|
|Disable implicit expansion within the specified function in the generated code|
Indicate that a MATLAB function is intended for code generation.
