p = randperm(n) returns a random permutation of the integers 1:n.
The randperm function calls rand. Here are two examples:

randperm(35)

ans =     33    26    18     5     4     1    23     6    14 25     7    
32     9    15    13     2    12    29    22

    28     8    16    30    34    10    17    21    24    31 20    
11    35    27    19     3

 randperm(5)

ans =    5     4     2     3     1
