一个多维极值求解算法（用连分式法求解目标函数的极值点）

注：to 站长，刚才上传的那个是多维极值求解的，这个是一维求解的，刚才颠倒了，抱歉 -_--a multidimensional Extreme algorithm (even with fractional method objective function of extreme points) Note : to head just upload the extreme that is multi-dimensional solution, the solution is one-dimensional, just reversed, sorry-_ -
