nonlineareq

代码说明：

  function g=nonlineareq(x) Here is an example of nonlinear system that can be solved by using the Matlab command "fsolve" written in the file called "solution.m" (see quasi-Newton or Levenberg-Marquardt methods). g(1)=x(1)-4*x(1)*x(1)-x(1)*x(2) g(2)=2*x(2)-x(2)*x(2)+3*x(1)*x(2)
