Is there a way to compute the n-point fft of an 1D array in MKL (C-language, Linux) for an arbitrary number of n?The problem is that i need to translate the matlab function fft(X,N) to use with the MKL-lib. The function inside matlab is described as : "fft(X...

I import my input data from two files I filled using fft() in Matlab, one with the real part and the other one with the imaginary part. The complex data is stored in tfNewComp. The final code should be able to work in 3D but for the time beeing I'm just trying...
What do you mean by "noisy"? Your calculation gives you the correct information, i.e., sum of harmonic sinusoidals. First of all, let's take a look at how your signal looks in time domain.
