without loop makes it quite difficult..is there any particular built-in function to do this?
You do know that Matlab most certainly uses while and for loops to multiply matrices internally. The vectorized solution is probably faster because of parallelization and other optimization tricks, which we could also implement with the proper toolboxes.
And please add an space to strfind, or else It will find fors and whiles inside comments and even parameter names. I was using a parameter "Uniform" of the function cellfun and it took me a while to realize why it was failing the first test.
very nice idea!
The first truly vectorized solution I've seen here without using for, while, cellfun, arrayfun, etc.
