Hi,
I need to create a 100*100 matrix with 3 conditions :
- elements on the diagonal are 0
- elements below the diagonal contain the column number
- elements above the diagonal contain the column number with minus sign
it may look simple but I am really new here so I hope someone could help me out :)
thanks in advance

n=100;
[a,b]=ind2sub([n,n],1:n^2);
b(b==a)=0;
b(b>a)=-b(b>a);
c=reshape(b,[n,n]);
