i have a matrix of doubles, and would like to find the statistics of each number or in other words, to find how many times each element has been repeated across the matrix and plot it. i have a solution with for loops but it's too slow. i am looking for a matlab solution that is not based on nested for loops.

Hi

I suggest you start by trying the hist function.
