这是利用matlab7.0软件对通信信号进行调制simulink仿真，它包括am,pm,fm,ask,psk,fsk,qpsk等调制方式，有利于学生自学和老师教学！(This is the use of software for communications matlab7.0 modulation signal simulink simulation, which include am, pm, fm, ask, psk, fsk, qpsk such as modulation and is conducive to student learning and teachers teaching!)

非线性动力学中lyapunov、duffing等方程的求解，详细Matlab程序(Nonlinear Dynamics lyapunov, duffing equations and other details Matlab procedures)

根据条形光波导折射率数据，分别针对宽高比a:b为1:1与 2:1两种情形，设计分析 ： 1. 满足单模与双模传输的 波导尺寸范围。（需要 给出色散曲线） 2. 针对两种情形，选取你 认为最佳的波导尺寸， 计算对应的模折射率。 （计算时假设上、下包 层均很厚）(According to the refractive index of the optical waveguide stripe of data, respectively, for an aspect ratio of a: b is 1: 1 and 2: 1 both cases, the design and analysis: 1. Meet single-mode and dual-mode transmission Bird size range. (need Given dispersion curve) 2. For both cases, you select That the best of the waveguide dimensions, Computes the corresponding mode refractive index. (Calculations assume that when the upper and lower package Layers are very thick))

本文档对MATLAB仿真做了详细全面的介绍，适合初学者学习使用(This document is a detailed simulation of the MATLAB comprehensive introduction for beginners to learn to use)

说明：  对指纹进行处理，指纹识别，带有GUI界面，但是需要付费才能得到代码(Fingerprint processing and fingerprint recognition)

说明：  讲述基于QPSK调制在高斯，瑞利，CorrRayleigh信道下的误码分析。(About QPSK modulation in the Gaussian, Rayleigh, the CorrRayleigh channel bit error analysis.)

遗传算法matlab实现，还有倒位操作。(Genetic Alogrithm using matlab, as well as changing-seat operation.)
