Hello, i have a matrix,H which have N rows and n columns.lets say N = 20 and n is 3. i would like to rearange only the rows in H, in a radom way. but keep every element in the say column he was before. so that h(1,:) will be moved to a radom place h(random number,:)
is there a built in function than can do this?
i think i know how to di it by my self, but can find anything bulit in.
thank u!

N=size(H,1);
H=H(randperm(N),:);
