I need to create a matrix that's 250X250. Also, I need to have the same number in every 50 rows, something like this:
111
111
222
222
333
333
How can I do that? Thank you!

Create a 250 by 250 matrix:
A = zeros(250)
And then to fill any 50 rows with a particular number:
A(1:50,:) = 1
This will fill rows 1 to 50 with the number 1. You can do this for any number then to complete your task. Hope this helps
