Hello all, I have a small point that stopping me in some ideas. It is about how to convert the binary lower triangle to xor upper triangular. For example: A = tril(randerr(4,4)); and then get A. I want the upper triangle = xor of A or we can say as conjugate A. The result if we XORed the Upper to Lower we get the zeros or ones.

If the question consists of converting lower triangular binary matrix into upper triangular one, then is it possible to use logical operation xor, there are two possible values in a={1,0}, the kernel is b=1, so xor(a=1,b)=0 and xor(a=0,b)=1.
n=10;
A=ones(n);
A=tril(A);
B=xor(A,ones(n));
diagonal elements can be adjusted with options of tril function.
