%How do I change this function so that it works for matrices of any size?
function [B] = Matrices(matrice)
B = matrice;
B(1,1) = 0;
B(1,2) = 0;
B(1,3) = 0;
B(2,2) = 0;
B(2,3) = 0;
B(3,3) = 0;
end
%So that calling this
[B] = Matrices([1 2 3; 4 5 6; 7 8 9])
%Will return
B =
0 0 0
4 0 0
7 8 0

function B = Matrices(matrice)
B = tril(matrice,-1);
end
