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.

When I try "If X is a matrix then Scilab equivalent for Matlab ifft(X) is fft(X,1,2,1)." I get the error:

-->X = ones(5,5);

-->X2 = fft(X,1,2,1);
!--error 999
fftw: Wrong values for input argument #3: Must be a divisor of 25.
