说明：  描述了基于瑞利信道下的频谱感知的问题，使用的蒙特卡罗法进行仿真。(Based on Rayleigh Road, described under the issue of spectrum sensing, the use of Monte Carlo simulation.)

This is a funciton programmed in matlab to Calculate Minimum Costs and Paths using Dijkstra s Algorithm. The function can input different data format. The output is easy to understand and can be used to analyze network feature for students to study.Several demos have been included in the source code.

一个 4fsk 的调制方式的程序 设计调制信号，共有4种频率,每个码元的发送时间和2ask是一样的 (A modulation method 4fsk in program design modulated signal, a total of 4 types of frequencies of each symbol transmission time and 2ask the same)

这是一份MATLAB基础课件，由于我也是初学者，这部课件讲的很浅显，但比较适合初学者对MATLAB所有功能的一个初步了解内容包括涵数值数组及其运算， M文件和面向对象编成， 字符串数组， 符号变量， matlab 绘图 及 Simulnk动态仿真。以及两个基本浅显的程序题。此为第 5章。(This is a basic MATLAB courseware, because I am also a beginner, this software is very simple-speaking, but more suitable for beginners of all the features of MATLAB, a preliminary understanding of the content including the Han and its numerical array computing, M documents and for object into string array, variable symbols, matlab graphics and dynamic simulation Simulnk. As well as the two basic procedures for simple questions. This is Chapter 5.)

三种方法实现数字下变频：直接法、bessel插值、多相滤波等(three method of DDC)

matlab遗传算法工具箱，在编程时使用遗传算法时，可以直接用工具箱中的函数(matlab genetic algorithm toolbox, use genetic programming algorithm can directly use the toolbox function)

主要用于故障诊断的神经网络预测KPCAcontourmap代码文件(Neural Network Prediction KPCAcontourmap Code File for Fault Diagnosis)

北大竞赛题,非常好的。好不容易才找到的东东！(North title race, very good. Hard to find the NEE!)

主要解决用MATLAB求解偏微分的问题，着重介绍PDE工具箱，十分适合初学者(Mainly to solve the partial differential use MATLAB to solve problems, focused on PDE Toolbox, is very suitable for beginners)

说明：  用于目标追踪的MATLAB实用程序，基于KALMAN方法实现(MATLAB for target tracking utility method implementation based on KALMAN)
