Generating sets of non repeating random numbers

Hi,
How do I create 10 sets of random numbers within a range such that after every set, the numbers previously generated can’t be repeated or generated again i.e if I generate [1,3,8,6] from the range [1:40] those numbers would be deleted from the range and can’t be generated again

Here is an example:
S=reshape(randperm(40),[],4);
All elements in S will be in the range [1 40] and unique. From this it follows that all 10 rows of S will also be unique.

Same idea applies, but cutoff the extraneous samples before reshaping. Example for 300 range and 27-by-9 matrix.
S=radndperm(300);
S=S(1:(27*9));
S=reshape(S,27,9);
