很多matlab的功能想用但不知道是那个函数怎么用，这资料给你提供了帮助(Many want to use matlab function but do not know how to use that function, which provides information to help you)

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 )
