This is a MuPad command. To run it, open a MuPad note book and run it there:

mupad %or click the app.

And for more info:

doc mupad

If you just want a random integer matrix in MATLAB look at randi

randi(10,2,2)

And for more info:

Thanks, and if I want an m by n matrix with each row having the numbers 1 to n in a random order?

[Sean de Wolski]

You could use randperm in a loop or:

m = 5;
n = 9;
[~,R] = sort(rand(m,n),2)
