Create aa difficult matrix in a loop

Hey all,

in general I dont have much problems creating a matrix with a loop, but I cant see the pattern here.

If loop is not the right answer here, maybe you could give me a hint for something else?

Thx !

There is no "if loop" in any programming language I know. You showed 3 different matrices. There is an infinite number of methods to create these 3 matrices with a certain number of input arguments. So what is the actual definition and what are the parameters for the 3 examples? There are some white and some light blue cells. Please do not let the readers guess the details.

Oh, I am sorry. I will edit right away.

With some bold guessing:

n = 2;
R = -ones(n+1, n, n+1);
v = 1:n+1;
for k = v
    R(v(v ~= k), :, k) = eye(n);
end
R = reshape(R, n+1, n*n+n)
