代码基于《用C++语言编写数学常用算法》/陈必红著。源码中定义了多种矩阵初始化函数，可以讲数组，文本文件等直接转换为矩阵。除了常用的矩阵运算分解等操作，增加了常用的矩阵点乘，叉乘，矩阵块移除等常用操作，在源文件中有详细注释。-Code based on the " write mathematical language commonly used algorithm C++" /Chen Hung forward. Defined in a variety of matrix source initialization function, you can tell arrays, text files directly into the matrix. Addition to the usual decomposition of matrix operations and other operations, increasing the common dot matrix, cross product, matrix blocks to remove other common operations, detailed notes in the source file.
