C/C++ Code Generation

Generate C code from MATLAB^® code

Generate C/C++ source code, static libraries, dynamic libraries, or executables from MATLAB code using the MATLAB Coder™ app or the codegen command. You need MATLAB Coder to generate standalone C and C++ code for supported functions.

For a list of functions that support code generation, see Function List (C/C++ Code Generation).
