I used Matlab Coder to convert a function containing FFT into C code.
But it is very slow.
I've checked some of the C code.
It looks like the FFT operation is not optimized.
I inquire if I can use FFTW or MKL. (I don't know in which menu of the coder app these functions are available.)
I can use both Matlab C Coder and Embedded Coder.
I need help with this issue.
