完整的矩阵类，实现的功能如下：

方阵、拷贝构造、初始化,分配矩阵数据的内存,并全部置0、将方阵初始化为方阵、设置矩阵个元素的值、得到知道元素的值、获取矩阵的列数、获取矩阵的行数、获取矩阵的数据、获取指定行的向量、获取指定列的向量、重载运算符 = 、重载运算符 ==、重载运算符 !=、重载运算符 +、重载运算符 -

重载运算符 数乘*、重载运算符 矩阵相乘*

矩阵转置。-integrity of the matrix type, function as follows : Lineup, copy structure, initialization, distribution matrix of data memory, All the home 0 to initialize arrays of arrays installed matrix elements of value, be aware of the value elements, Access Matrix number, access to the Matrix a few, access to the data matrix, the designated access vector, The designated access vector, heavy Operators =, operator == heavy, heavy load Operators! =, heavy Operators, Heavy Operators - Heavy Operators multiply *, heavy Operators matrix multiplication * matrix transpose.
