1．　　在程序运行过程中首先根据目标函数和等式约束条件写出拉格朗日函数，确定出新的目标函数的维数和系数，并输入到程序中从而得出结果。在本程序中，用到了列主元高斯消元法求解方程组。-1. First, the program is running according to the objective function and equality constraints to write the Lagrangian function, to determine a new dimension and the objective function coefficients, and enter into the program, and thus the outcome. In this procedure, used in the column PCA Gauss elimination method for solving equations.
