reordering

I have an NxM matrix in Matlab that I would like to reorder in similar fashion to the way JPEG reorders its subblock pixels:

(referenced from here)

I would like the algorithm to be generic such that I can pass in a 2D matrix with any dimensions. I am a C++ programmer by trade and am very tempted to write an old school loop to accomplish this, but I suspect there is a better way to do it in Matlab.
