Description:
//奇异值分解法求广义逆
//本函数返回值小于0表示在奇异值分解过程,
//中迭代值超过了60次还未满足精度要求.
//返回值大于0表示正常返回。
//a-长度为m*n的数组，返回时其对角线依次给出奇异值，其余元素为0
//m-矩阵的行数
//n-矩阵的列数
//aa-长度为n*m的数组，返回式存放A的广义逆
//eps-精度要求
//u-长度为m*m的数组，返回时存放奇异值分解的左奇异量U
//v-长度为n*n的数组，返回时存放奇异值分解的左奇异量V
//ka-整型变量，其值为max(n,m)+1
//调用函数：dluav()-//Singular value decomposition method for generalized inverse// this function return value is less than 0 in the singular value decomposition process,// in the iterative value of more than 60 are unable to meet the precision requirement.// Return value greater than 0 indicated a normal return.// a-length m* n array, return its diagonal singular value is given followed by the remaining elements to 0// m-matrix rows// n-matrix the number of rows// aa-length n* m array, retrievable storage A generalized inverse// eps-precision// u-length m* m of the array, return deposited the left singular value decomposition singular quantity U// v-length of n* n of the array, return deposited the left singular value decomposition singular volume V// ka-integer variables, its value is max (n, m)+ 1// call the function: dluav ()

Description: //奇异值分解法求双精度浮点数矩阵的广义逆
//功能：利用奇异值分解求解一般的m×n阶实矩阵A的广义逆A+。
//方法说明：设m×n阶实矩阵A的奇异值分解式为
//其中 Σ = diag(σ0, σ1, ……,σp)(p≤min(m,n) -1 )且σ0≥σ1≥……≥σp＞0
//设U = （U1,U2）,其中U1为U中前P+1列列正交向量组构成的m×(p+1)矩阵；V = (V1，V2)，其中V1为前P+1列//列正交向量组构成的n×(p+1)矩阵。则A的广义逆为：
//A+ = V1ΣU1T
//以求3×4矩阵的逆矩阵为例。-pseudo-inverse matrix
