ifft (Matlab function) Inverse discrete Fourier transform

## Matlab/Scilab equivalent

Matlab | Scilab
    ifft(A[,...])
    fft(A,1[,...])

## Particular cases

Y = ifft(X):

  If X is a vector then Scilab equivalent for Matlab ifft(X) is fft(X,1). If X is a matrix then Scilab equivalent for Matlab ifft(X) is fft(X,1,2,1).

Y = ifft(X,n) / Y = ifft(X,n,dim) / Y = ifft(X,[],dim):

  There is no Scilab equivalent for all these Matlab uses of ifft, in these cases, use mtlb_ifft instead.
