I'm an italian boy, so i'm sorry if i don't speak english very well.
I have a model in Simulink that takes one vector of 128 values and calculates the FFT algorithm.
But the Matlab FFT algorithm, accepts, DOUBLE values in input, and instead i must use INT values.
I can't use C function (limitation),so i can use only matlab code.
Does exist an FFT algorithm that accepts INT values or can someone write me an alternative FFT algorithm ???
Thank you very well !
