Hi, is there a way to put bounds not only on a single variable of a Limit State Function (LSF) but directly on a part of it?

For example, if the LSF is g(x) = ‘[X(:,1).*X(:,2) - X(:,3).*X(:,4)] - X(:,5)’, is there a way to put a lower bound at the whole function in the brackets [X(:,1).*X(:,2) - X(:,3).*X(:,4)] ?

Thank you.
