文件为C#矩阵运算类，包含了多种形式的矩阵定义，能够进行多种矩阵运算，如矩阵四则运算、求逆、转置等，十分方便用于实际开发。(File for the C# matrix operations class, contains the definition of various forms of matrix, to carry out a variety of matrix operations, such as matrix arithmetic, inversion, transpose, etc., is very convenient for actual development.)

阵列处理作业，MVDR或者其他高分辨方法，由于信号源无法确定，造成估计误差，采用对角加载的 增加单位阵法 ,以及 六源准则法 获取优化结果。(Array processing, MVDR, or other high-resolution method, the source can not be determined, resulting in the estimated error, the use of diagonal loading ' to increase the unit matrix method' , and ' six-source criteria method' to obtain optimal results.)
