实现四位矩阵a和四位矩阵b的乘法，最后存储在c矩阵中-Achieve four matrices a and b, four matrix multiplication, and finally stored in the c matrix

主要写了一些c#通用函数类库源码，比如矩阵加法，减法，乘法，求逆等一些程序-Mainly write c# generic function class library source code, such as matrix addition, subtraction, multiplication, inversion and some programs

基于C++的复数运算，定义了加减乘除取实部虚部，定义了2×2阶复数矩阵的乘法 内附详细注释-The basic calculation based on C++. Define basic calculation between complex number, including+,-,*,/. Define the multipy between two 2*2 complex matrixes.
