Replicating a vector while summing an increasing value

3 views (last 30 days)
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.

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

a = [ 7 8 9 7 8 9];
bsxfun(@plus,a,10*[1:5]')

Try this:
a=[7,8,9,7,8,9]
n = 8; % Whatever you want.
firstColumn = (0:10:10*(n-1))'
b = repmat(firstColumn, [1, length(a)]) + repmat(a, [n, 1])
