I want to create the upper triangle matrix only directly in matlab and reflect it to make a full square matrix. I will assign numerical values to all the variables listed in the matrix.

Hi,
Consider the upper triangular matrix created below:
A = [1 2 3 4; 0 5 6 7; 0 0 8 9; 0 0 0 10];
To create the mirror image of upper triangle into the lower triangle, use the code below:
for i = 1:size(A,1)
for j = 1:size(A,1)
if j < i
A(i,j) = A(j,i);
end
end
end
Hope This helps.
