FFT has a size not equal to 2^N

Started by gihan_gomah May 29, 2008
Hi all-
I want to apply the FFT to a data has a size not equal to 2^N in a
simulink model and I want to generate code from this model. I used the
Matlab Fcn block and although it succeded in the simulation , the code
generation doesn't accept it. I knew that the best method to do this
operation is to use the S-function Builder but I don't know C language
and I need to Know the code and the libraries needed to make this
operation.
