fft (Matlab function)

Discrete Fourier transform

Matlab/Scilab equivalent

Matlab Scilab
fft(A[,...])
fft(A,-1[,...])

Particular cases

Y = fft(X)

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

Y = fft(X,n) / Y = fft(X,n,dim) / Y = fft(X,[],dim)

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