在运行fsolve中出现以下提示是什么意思呢？
采用fsolve解非线性方程组，出现以下提示
Warning: Default trust-region dogleg method of FSOLVE cannot handle non-square systems; using Gauss-Newton method instead.

运行后出现了
Optimization terminated: directional derivative along search direction less than TolFun and infinity-norm of gradient less than 10*(TolFun+TolX).或
Optimization terminated: magnitude of search direction less than TolX.

请问是什么意思呢，如何解决呢
