多变量寻优的源码，包括基本算法如下：DFP法（又称变尺度法），BFS法、一阶梯度法，共扼梯度法。-multivariate optimization of the source code, including basic algorithm is as follows : DFP Act (also known as the variable scale), BFS, a ladder degrees, a total of the accused gradient method.

变尺度法DFP求函数极小点（个人编写，改变函数、即可使用）-DFP DFP minimum point of a function

DFP法，变尺度法，优化算法的一种，具有二次收敛性，若目标函数为二次正定函数，经有限步可达到极小点-DFP method, variable metric method, an algorithm with quadratic convergence, if the objective function is quadratic positive definite function can be achieved by the finite step minima
