MATLAB: How to write a function that randomly sorts numbers into equal groups

Question

I want to write a function that randomly sorts numbers 1-72 into 6 equal groups of 12 (with no repeats).

Any help would be great,

Thanks.

Answer 1

N=72; G=6;                        % constants per problem definition
rnv=reshape(randperm(N),[],G);    % separated into G columns
