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?
