Hi;

This question seems easy but do you know how to find all possible permutations for FOUR variables where each variable can take a value from 1 to 10. I want to put all posible permuatations in a single matrix.

If you want each of four variables to be able to assume any value from 1 to 10, independently of the other variables, then you want all possible combinations, of which there are 10^4 = 10000. If you want to restrict them so that no two are alike, then there would be 10!/6! = 5040 of them. Which, if either of these, are you interested in?

If it's the second of the above, you will find a function that does this at:

Thanks a lot Roger; this is exactly what I needed.
