迪杰斯特拉和克鲁斯卡尔算法的Matlab实现。包含dijkstra.m和Kruskal.m文件，可用matlab直接打开，添加到运行路径后即可；或者用文本打开，复制代码。(Realization of Dijster Straw Algorithms in MATLAB)

最经典AdaBoost实现，适合初学，有大量详细的注释，容易理解(This a classic AdaBoost implementation, in one single file with easy understandable code. The function consist of two parts a simple weak classifier and a boosting part: The weak classifier tries to find the best threshold in one of the data dimensions to separate the data into two classes-1 and 1 The boosting part calls the classifier iteratively, after every classification step it changes the weights of miss-classified examples. This creates a cascade of "weak classifiers" which behaves like a "strong classifier" 。)

this programs explain the basic functionality of QPSK Modulation and Demodulation program. Check this.

DS-CDMA中匹配滤波器误码率分析，只是一直为零，感觉没有错阿。(DS-CDMA matched filter error rate analysis, but the zero, A feeling nothing wrong.)

基于轮廓波的多聚焦图像融合，采用MATLAB语言(image fusion by contourlet)

时频分析中维格纳 分布 ，以及维格纳分布的改进方法！( Joint Time-Frequency Analysis)

本程序是用来做基于matlab的龙格库塔数值计算。(This procedure is used to do the calculation based on the Runge-Kutta numerical matlab.)

对原始信号进行四相相移键控调制，然后加入高斯白噪声，对加噪信号进行解调，对比解调信号与原始信号，计算误码率(The original signal quadrature phase shift keying modulation, and then adding Gaussian white noise, plus noise signal is demodulated, comparing the demodulated signal with the original signal, bit error rate calculation)
