本程序为利用广义逆矩阵法求解朝顶非线性方程组，里面调用了其他三个函数，非别为一般实矩阵的奇异值分解、奇异值分解求一般实矩阵的逆矩阵、广义逆矩阵法求线性超定方程组。-The procedure for the use of generalized inverse matrix method for solving nonlinear equations toward the top, which calls the other three functions, not as a general real matrix non-singular value decomposition, singular value decomposition seeking general real matrix inverse, generalized inverse matrix method of linear overdetermined equations.
