I have code that extracts a number of features, including gammatone cepstral coefficients using the matlab function gtcc. This section is currently too slow for my application, so I'm trying to find ways to speed up the process, including compiling it to mex. In the documentation, extended capabilities lists code generation using the matlab compiler.
I can't get this to work. I've tried calling using a second function without success.
I get the following error, which I do not know how to overcome...
"Failed to compute constant value for nontunable property 'WindowLength'. In code generation, nontunable properties can only be assigned constant values."
