Hello,

How can I randomly select an element of a matrix ?

Best answer by Fred_Kohlhepp

There is a function that returns a random number between ceertain limits. You colud use that and the ceil and floor functions to make it an integer, then use that as an index to the matrix.

    You create two integer random numbers within the valid ranges, one for row and the second for the column index.

      Just wanted to get sure that what I post works, whatever you have ORIGIN set to.

      Default value for ORIGIN is zero which is perfectly OK and I IMHO there is no reason to change that, but some people like it to be set to one.
