使用matlab仿真OFDM。其中描述了OFDM的基本原理，含详细的公式推导过程。在文章最后附有matlab代码，并且有仿真结果可参考。(Matlab simulation using OFDM. Describes one of the basic principles of OFDM, with a detailed formula derivation process. At the last article with matlab code, and have the simulation results can be found.)

一本matlab rune教材，有很多实例，比较简单，学习过程中可以不断尝试。(A book about matlab,it can be used by those who knows little about matlab.)

主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。 (Main Content (signal_analyzer.rar) as follows: test1.txt the first time as t, 0.001s for the step the second as the input signal the third as the system output signal. signal_analyzer.m first test1.txt the data read into the workspace, and then FFT, the frequency of the two signals, the output amplitude for input attenuation (db), the output of the input phase difference.)

基于levelset的测地活动轮廓 matlab源码，可实现多目标轮廓的 提取。对噪声图象具有良好的鲁棒性。但是计算量较大，耗时过多(levelset based on the geodesic active contour Matlab source, more achievable goal contour extraction. Image noise is a good robust. However, the large amount of calculation, time-consuming excessive)
