作为一个功能强大的工具软件，Matlab具有很强的图形处理功能，提供了大量的二维、三维图形函数。由于系统采用面向对象的技术和丰富的矩阵运算，所以在图形处理方面即常方便又高效。(As a powerful software tool, Matlab has a strong graphics capabilities, providing a large number of two-dimensional, three-dimensional graphics functions. Since the system uses object-oriented technology and rich matrix computation, graphics processing, so that is often convenient and efficient.)

Ansys动力分析中大质量法的应用,主要用于地震动计算,行波及多点输入的实现(Dynamic Analysis Ansys massive application of the law, mainly for ground motion calculation, OK affecting the realization of multi-point input)

本文件介绍了matlab的数值计算和编程，利于加深matlab的学习(This document describes the Matlab numerical computation and programming, to help deepen the study of the matlab )

本代码是《通信信号处理》课程的大作业相应的代码。主要是通信信号发射端的仿真，具体功能是：1. 产生任意长度的伪随机序列，将序列映射为I,Q两路的信号，2.均方根升余弦滤波器成型. 3.经过通带衰减为3dB的倾斜滤波器（模拟信道衰落效果）4.插零，半带滤波器升抽样。 5.NCO处理单元调制(This code is communication signal processing courses corresponding to the large code. Mainly is the simulation of the communication signal transmitter, the specific functions are: 1. Produce arbitrary length of the pseudo-random sequence, the sequence mapping for the I, Q two-way signal, 2. Raise the root-mean-square filter forming 3. After passband attenuation 3dB tilt filter (analog channel fading effect) 4. Insert zero, half-band filter l sampling. 5. NCO processing unit modulation)

说明：  对一个非线性的滤波器设计进行优化，使得设计出的滤波器与给定指标最接近且要求优化变量取离散值得优化设计问题(Of a non-linear filter design is optimized, making the design of the filter and to set targets and optimize the variable closest to the requirements and obtain the optimal design of discrete worth)
