Hello Dear Experts,
I am given an image, and after making it of type double I want to do fft2(img). But then I want to use the fftshow(img) Matlab tells me there is not any function with this name.
In 2010b there was such function, I am using 2011b release. Please guide what to do and maybe there is another function who support backward compatibility. Thanks a lot in advance.
P.S
If you have your own best practice, will be more than happy to learn from your experience.

fftshow() is not a Mathworks-provided function.
You can find a fftshow() function here. Whether it is the one you need is something you will need to test for yourself.
