24 Apr 2009 N-dimensional Fourier interpolation Performs N-D FFT interpolation with upsampling, downsampling, or mixed up- and downsampling Author: Matthias Schabel

Matthias, I cannot get this to work. The example image posted seems to interpolate the peaks dataset by a factor of two. But when I run the following code, I don't get the same result:
>>> figure; subplot(1,2,1); imagesc(peaks);
>>> subplot(1,2,2); imagesc(fftInterpolate(peaks,2));
what's going on?
