Hi all matlab geeks out there,

I have a code for transformation of imagethat involves translation and rotation of image, since the number of data points are 15 million, I needed to grip the image first, however my current code has a a processing time of over 20 days, I am pretty sure something is wrong the way ive written my code can any help out ?I've attached the code in pdf file. THANKS MUCH

Take a look at scatteredInterpolant() or griddedInterpolant() to turn your list of xyz coordinates and colors into a rectangular image.

thanks, but I do need to grid the coordinates before I can do that, and they don't seem to process soon enough, I am thinking of giving some more time to improving the code to make processing faster before having it run at a super computer but i dont think that would be necessary, any suggestions ?
