Randomly makes matrix rows as one vector

Hello all, I would like to work on a marix that should be converted to on vector (by rows), but my question here is how I can convert these rows in my matrix to one vector but randomly sorting, I mean that it should be not [row1, row2,.....] but like for example [row2, row8, ... so on].

Hint

    M = magic( 7 );
    R = M( randperm(7), : );

Add on the line

   M_new = reshape(R',1,[]);

to make it "on(e) vector".
