Hello people,
I would like to know if someone has a quick way of writing this matrix using 'ones' and 'zeros':
Many thanks!

One possibility is to concatenate them at the same time that they are created using zeros and ones. So something like this:
Aeq2 = [ones(1,9) zeros(1,10) 1 ; ...
zeros(1,9) ones(1,10) -1];

You can fill all entries with either 'ones' or 'zeros', then change the rest:
Aeq = zeros(1,20);
Aeq (1,1:10) = ones;
