I have a 2D array where the axes are positions (x, y). I wish to perform a Fourier transform along the x axis alone resulting in an array (Kx, y), where Kx is momentum, the Fourier transform of x.
In python this is a simple command as you can pass which axis to perform the transform along as an argument to the FFT function.
Is there a way to do this with the MKL library?
Thanks very much,
