I don't know why I can't figure this out! I'd swear I've done it before.
What's the trick to sorting columns in random order? I have a matrix with
many columns. Suppose the matrix is called 'X'. It seems like I should
be able to use something like this:
[S, I] = sort(rand(size(X)));
Then I can use 'I' to sort the columns of X, right? But how? I just know
there's an easy trick.
Thanks in advance for breaking my mental block.
Mike
