利用Matlab提供的firhalfband函数设计阶数为16、通阻带容限为0.0001的半带滤波器。 仿真测试滤波前后的信号时域图，绘制滤波器的频率响应特性图。( Matlab provides firhalfband function design of the order number is 16, stopband tolerance of 0.0001 half band filter. simulation test before and after filtering signal time domain graph, drawing filter frequency response characteristics of the figure.)

可以实现矩阵的奇异值分解，当矩阵较大时分解速度较慢，仅供研究矩阵奇异值分解的同仁参考。(This program can realize the singular value decomposition of a rectangular matrix. When the matrix size is large, the decomposition speed is slow. This program is just a reference for those who are interested in singular value decomposition of a matrix.)
