Automatic Complex Conjugate in ftt

So I am computing the fft of an array containing vectors. The documentation says that the fft treats each collumn as a vector and computes the fft of each collumn. This means that the following should be the same:

% F1 and F2 should be equal

data = rand(4,100)

F1 = fft(data')' ; % F1

F2 = zeros(size(data)) ;
for n = 1:4
    F2(n,:) = fft(data(n,:)) ;  % F2
end

But they are not equal. In fact, F2 is the complex conjugate of F1. Does anyone know why this is this happening?

Hello Ha Oe

the quote command is not just the transpose, it's the complex conjugate transpose (Hermetian conjugate). For the straight transpose, use .' (dot quote).

Thank you. That now all makes sense.
