How do I create a matrix with a randomized permutation of integers?

Alternatively: What is the matrix equivalent of randperm(n,k)?

I can't figure out a simple way to do this.

Can you accomplish what you want by simply reshaping a random vector into a matrix?

reshape(randperm(16,16),[4,4])

ans =

     4    12    11    15
     7     5    13     9
    14     8     2     1
     6    10     3    16

Yes, this is just the thing I need! I never knew there was such a function, thank you :)
