I have x=[1 2 1 1; 4 5 1 1 ; 7 8 1 1]. I want a matrix in which this matrix repeats itself 10 times using repmat function and with each repetition the first and second columns of the basic matrix ,that is x, increase by 5. Thus my fourth, fifth and sixth row (first repetition) will be [6 7 1 1 ; 9 10 1 1 ; 12 13 1 1] .In second repetition ,that is 7th,8th and 9th row, it would be [11 12 1 1 ; 14 15 1 1 ; 17 18 1 1 ] and so on till 10 repetitions are performed

y = repmat(x,10,1);
y(:,1:2) = y(:,1:2) + repmat(5*floor((0:29).'/3),1,2);
