If I understood you correctly using "imfilter" with 'same' property would solve your problem.
I couldn't find "install_matlab". I'm using R2010b. Any other ideas?

Thanks again. When I came with the idea of splitting the N/2 sample I had in mind a scaled DTFT. Which is basically what you did...
Thanks for helping. I can't understand your proof, I guess it has to something to do with the limited platform. Do you have an e...
That wouldn't work for even vector. Try it yourself and you'll see that after you apply IDFT you get a complex vector. I think t...
