Code Generation

Generate C/C++ code and MEX functions for toolbox functions

MATLAB® Coder™ generates standalone C/C++ code from Wavelet Toolbox™ functions that have been enabled to support code generation. Using the toolbox with MATLAB Coder, you can generate ANSI-compliant C/C++ code or MEX functions. Wavelet Toolbox code generation supports these workflows:

  • 1-D and 2-D critically sampled discrete wavelet transforms (DWT)

  • Nondecimated 1-D wavelet transform (MODWT)

  • Nondecimated 1-D wavelet packet transform (MODWPT)

  • 1-D and 2-D wavelet denoising
