B = blkproc(A,[m n],fun)

Can some body tell me how this function operates especially that it is not clear in the documentation. I just need to understand WHERE will the function be applied on "A". Say we have [3 3], will the function be applied ONLY on the top left matrix "A" with dimensions 3X3? Or, will it move after that?... more »

Oh, and since 7.1 doesn't run on Vista, and I thus have to use 7.6, this means that my new state of the art laptop runs equally fast as my three years old shitty HP. This sucks.... more »
