out = reshape(ones(251,1)*P(:)',1,[]);
or
out = kron(P(:)',ones(1,251));

thank you
if PN1=<255x1 double> so i am getting this error ??? Error using ==> mtimes Inner matrix dimensions must agree.
Error in ==> repof at 30 out = reshape(ones(250,1)*PN1,1,[]);

the bit we are adding it is adding in the next colum but the bit should add in between P[1 0 1] we are creating a matrix it should add in between the bits but we are creating < 255x250 double> 1 1 1 1 0 0 0 0 1 1 1 1
