Problem using fzero in classed method

Hello, I am trying to apply fzero() to a function defined as Methods (Access = private) in a classdef, without success, here attached the .m file.

The class myclass contains: - two public methods(oper and testZero) - two private methods (setb and valzero)

I have a problem with using testZero which applies fzero to valzero. I suppose I am declaring in a wrong way the fzero parameters.

Could you please advice?

Thanks a lot in advance Best regards, P

av=fzero(@valzero,obj,2); is only going to pass one parameter to valzero, but you defined valzero as needing two parameters, obj and a. Perhaps you want

av = fzero(@(x) valzero(obj,x), 2);
