I am using randperm to generate different random permutations (subset of the data) from a data set. However even after 2 iterations it is generating the same combination of the number. For eg: the desired output would be like p={1,3,5,6,9,10},{4,6,7,2,1,3}... however i am getting p={1,4,5,7,8},{1,4,5,7,8}. its the same sequence i am getting.

for k=1:3
out{k}=randperm(10,5)
end
celldisp(out)

Are you resetting the random number generator in between iterations?

You can use two different RandStream, one for the random sequence generation, one for randperm.
