This functionality has been around on the File Exchange for years. For instance, you might take a look at my RANDSWAP function

or RANDMAT by Peter Bodin

Here is the rather trivial one-liner for shuffling any array X (numbers, ND, cell, string, whatever):

X(randperm(numel(X)) = X ;

which maintains everything, except the order!

Your help section is pretty good; I'd suggest you try to follow ML standards, e.g., by creatin a proper H1 line, and example, and a See Also section (take a look at the help of any of the main ML functions)
