MATLAB_introduction

说明：  是建议光纤模型的程序，和comsol相关的程序，并引入边界条件(it s about the codes for the model of optical fiber,connecting with thes software comsol. the boundary is involved)

输入信号的时域和频谱分析 输入信号为ft=[5cos(600*pi*t)+4cos(90*pi*t)+9]/18 输入信号为高频和低频信号的叠加：高频300Hz，低频45Hz( Of the input signal in time domain and spectral analysis of the input signal is ft = [5cos (600* pi* t)+4 cos (90* pi* t)+9]/18 input signal for the high-frequency and low frequency signal superimposed: frequency 300Hz, 45Hz low frequency)

研究生一门课程的小作业，很全，是关于模拟退火算法的(Postgraduate course of a small job, very full, the simulated annealing algorithm)

ca码的生成，还有跟踪环路的仿真，具有一定的参考价值(ca code generation, as well as tracking loop simulation, has a certain reference value)

说明：  混凝土随机骨料投放matlab程序，主要用于生成混凝土粗骨料随机分布的二维几何模型。还有ABAQUS参考书籍及学习代码。(The random aggregate concrete matlab program is mainly used to generate a two-dimensional geometric model of the random distribution of concrete coarse aggregate. There are also ABAQUS reference books and learning codes.)

matlab 简易教程，选修课上的电子版教案，简明易懂，很多例子直接可以借用，真的不错！(Layman' s Guide matlab, elective courses on the electronic version of lesson plans, easy to understand, many examples can be used directly, really good!)

这是关于直接序列扩频通信系统的DS-CDMA方式的仿真设计，系统主要分为发送机和接收机两部分，包括17个可用于SIMULINK仿真的S-FUNCTION代码M文件，和一个MATLAB源程序的DOC文件，程序都有详细的注释。(This is a direct sequence spread spectrum communication system on the DS-CDMA mode simulation design, the system can be divided into two parts, transmitter and receiver, including 17 for the S-FUNCTION SIMULINK simulation of M code files, and a MATLAB source code The DOC file, the program has detailed notes. 朗读 显示对应的拉丁字符的拼音 字典- 查看字典详细内容名词0.directness0.immediacy形容词0.direct0.immediate0.first-hand0.plump副词0.straight0.right0.slap )
