I am trying to do a 3D fft on some data using the built in GPU toolbox of 2011a and am having some trouble. Since the fftn function doesn't exist I find myself needing to do fft2 followed by fft. However, since "permute" doesn't seem to exist for GPU arrays either, I have to reshape the [l m n] matrix into a [l*m n] matrix, transposing it, applying fft, transposing back and reshaping back. Is there a more elegant/less asinine way of doing this?
