we have seen the function triu(A,k) which extracts upper triangular part of A. But i have to write my own function with the header U = myTriu(A,k) which does the same thing and apply it with A= (2 5 6 4 8 9 10 15 12),k) where k=-2,-1,1
Could anyone help me,please?

I think the first code you posted is not relevant to this question and the second code is written in C++ for k = 0 case.
You may use the following code which has a slight modification (checking for i + k > j) for all values of k
function U = myTriu(A,k)
for i = 1: size(A,1)
for j = 1:size(A,2)
if i + k > j
A(i,j) = 0;
end
end
end
U = A;
end
