Hi, I am using the FFTW.jl package. If I have a vector, say

x = rand(100)

How can I compute its discrete Fourier transform values in-place ? The command

fft(x)

returns a new array but leaves x intact.

This brings me to my second question, or comment, that often, these excellent libraries in Julia do not come with a documentation that lists the various functions, like in Java or Matlab. Does FFTW.jl have one such list ?
