WebJul 31, 2013 · It seems that even when working with theoretical data sets with exactly the same PSF curve, just different sizes arrays of zeroes outside the PSF point, the fourier transform gives different results. Since it is the same PSF, I assume that the resolving power should be the same for each data set. http://matlab.izmiran.ru/help/toolbox/images/psf2otf.html resync logitech keyboard k330
