Grouping Data in a Matrix in MATLAB
I've got a really big matrix which I should "upscale" (i.e.: create
another matrix where the elements of the first are grouped 40-by-40). For
every 40-by-40 group I should evaluate a series of parameters (i.e.:
frequencies, average and standard deviation).
I'm quite sure I can make such thing with a loop, but I was wondering if
there was a more elegant vectorized method...
