You can generate random permutations using MATLAB's randperm function. Unfortunately, thius function is quite inefficient since it is implemented by sorting a list of random numbers. This requires time O(n * log(n)).
Using the Knuth shuffle algorithm this operation only takes time O(n). This package implements the Knuth shuffle.
Usage: Simply use randpermquick(n) instead of randperm(n).
Note that the file randpermquick_helper.c has to be compiled before randpermquick can be used.
