Code Generation

Generate C code and MEX functions for toolbox functions

MATLAB® Coder™ generates standalone C code from Image Processing Toolbox™ functions that have been enabled to support code generation. Using the toolbox with MATLAB Coder, you can generate ANSI-compliant C code or MEX functions.
