Hi!
I was wondering how you can find zeroes to a function of two variables. I use Matlab. This is the function: Z = 2*A.*(A+B).*(2*A+B)./(B.*B).*(0.25*A.^(3)+4*(2*A+B).^(3)+0.25*(A+B).^(3))14.44; I know that A and B are positive. But I only know of inbuilt functions and algoritms for finding zeros for functions of ONE variable.. Do you guys know any?

Normally, you need two equations to minimize for two variables for a global solution.
