I try to port some new (R2015b) code using randperm(n,k) back to pre-R2011a. And initially i thought i could use r = randperm(10); r(1:4); as replacement for randperm(10,4) but then
>> rng(11313)
>> randperm(10,10)
ans =
10 1 7 8 5 6 3 9 4 2
>> rng(11313)
>> randperm(10)
ans =
9 1 10 6 7 3 8 2 5 4
i cannot see a structure, how randperm operates.

We cannot have a look into the randperm function. So if it is essential for you program to produce the same sequence of random numbers, you have to use
r = randperm(10); r(1:4);
in your program, also in the R2015b version.
