The program reads n-size matrix from text file, Finds the upper diagonal matrix. Finds the sum of the elements for each column and finds the maximum of each column. In this project explained opening and cloding text files.-The program reads n-size ma

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 s
