MATLAB: Replicating a vector while summing an increasing value

Question

I have this vector: a = [ 7 8 9 7 8 9]; and I would like to obtain the following vector:

b= [ 7 8 9 7 8 9; 17 18 19 17 18 19; 27 28 29 27 28 29; 37 38 39 37 38 39 …]

I am replicating the vector and then summing 10 for each line (for n lines). I would like to do this without using loop iterations. How can I do it? Thank you so much.

Answer 1

This works:

a = [ 7 8 9 7 8 9];
n = 4;
b = bsxfun(@plus, a, [0:10:n*10]');
