Organize matrix in a random way

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.

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