MATLAB是一套功能十分强大的工程计算及数据分析软件,具有友好的可视化编程界面及接近数学表达式的自然化语言。针对信号与系统中傅里叶变换具有抽象度高、难于理解的特点，利用MATLAB强大的信号处理功能、阶跃响应，微分方程，卷积定理的内容，通过MATLAB 程序实现。本文介绍了MATLAB在信号与系统仿真中的应用,该软件在通信电子类课程中应用越来越广泛,通过几个典型实例来重点研究。 关键词：MATLAB；阶跃响应；微分方程；卷积；信号与系统；仿真 (MATLAB is a very powerful engineering calculations and data analysis software, with a friendly interface and visual programming language close to naturalizing mathematical expressions. For the Fourier transform of signals and systems with a high degree of abstraction, it is difficult to understand the characteristics, the use of the powerful MATLAB signal processing functions, step response, convolution theorem content differential equations by MATLAB program. This article describes the application of MATLAB in signal and system simulation, the software in the electronic communications courses in applied more widely, by focusing on a few typical examples. Keywords: MATLAB step response signals and systems convolution differential equation simulation )

该程序是LWSG_NMF方法（局部加权稀疏图正则非负矩阵分解）的matlab实现，可根据所需参数，进行设置(The program is LWSG_NMF method (locally weighted sparse graph regular NMF) matlab implementation, according to the required parameters, set)

说明：  若非奇异矩阵A能够分解为一个正交矩阵Q与非奇异上三角矩阵R的乘积，即： A=QR。则称其为A的QR分解。 实现QR分解的方法有很多种，包括Givens变换法，Householder变换法，Schemit正交化法。具体原理可以参考《矩阵论》（程云鹏，西工大出版）教材，这里仅给出三种实现QR分解的程序。(If nonsingular matrix A can be decomposed into a product of orthogonal matrix Q and nonsingular upper triangular matrix R, that is: A=QR. It is called QR decomposition of A. There are many methods to realize QR decomposition, including givens transformation, householder transformation, and scheme orthogonalization. The specific principle can refer to the teaching materials of matrix theory (Cheng Yunpeng, published by Xigong University). Here, only three kinds of QR decomposition procedures are given.)
