此包包含了众多矩阵处理程序，能够满足矩阵处理的一般要求，由于将各功能分开到不同的“.cpp”文件中，故使用时需要用户自行选取更换合适自己使用的“.cpp”文件。其中，矩阵功能有：输出矩阵、矩阵转置、矩阵归一化、判断矩阵对称、判断矩阵对称正定、全选主元法求矩阵行列式、全选主元高斯(Gauss)消去法求一般矩阵的秩、用全选主元高斯-约当(Gauss-Jordan)消去法计算实(复)矩阵的逆矩阵、用“变量循环重新编号法”法求对称正定矩阵逆、特兰持(Trench)法求托伯利兹(Toeplitz)矩阵逆、实矩阵LU分解、用豪斯荷尔德(Householder)变换对一般m*n阶的实矩阵进行QR分解、对称正定阵的乔里斯基(Cholesky)分解及求其行列式值、一般实矩阵的奇异值分解、广义逆的奇异值分解。-This package contains a number of matrix processing, matrix processing to meet the general requirements, due to the separation of functions to different ". Cpp" file, so the need to use their own user-selected replacement suitable to use ". Cpp" files. Among them, the matrix function: output matrix, the matrix transpose, matrix normalized to determine the matrix symmetric, symmetric positive definite matrix to determine the whole pivoting method for the matrix determinant, full pivoting Gauss (Gauss) elimination method for the general matrix of rank, with full pivoting Gauss- Jordan (Gauss-Jordan) elimination method to calculate the real (complex) inverse of a matrix, with a "variable cycle re-number method" method for the symmetric positive definite matrix inverse, Portland hold (Trench) method for the Tuobo Leeds (Toeplitz) matrix inverse real matrix LU factorization, with high Siheerde (Householder) transformations of the general order of m* n matrix QR decomposition of real symmetr
