<br>
is there a simple way to perform a fourier transform of a 2D vector in<br>
only one dimension? Ie. transform the function f(x,y) in realspace (x,y)<br>
to f(k_x,y) in k space in the x direction and realspace in the y<br>
direction? I'd like to use FFTW for preference, since that is<br>
implemented on the cluster that I'm working with.</blockquote><div><br></div><div style>I do not know of one other than repeated calls to the 1D transform. If you can find</div><div style>it in the FFTW API when could put it in.</div>
