I'm facing a problem in dividing an image into non overlapping blocks. I am supposed to take a Fourier transform of the divided blocks.can i use "blockproc" to do this?

Note that you will need the Image Processing Toolbox to use this function.

You can use mat2cell() or indexing(). Both of these methods are shown in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_split_an_image_into_non-overlapping_blocks.3F
If you also want to call a function on each block, then you can use blockproc() as illustrated in my two attached demos.
