本源码是用于现代谱估计的一种方法：巴特利特主分量估计算法，对3个频率进行分辨。(The source code is for a modern spectral estimation methods: Bartlett principal component estimation algorithm, the three frequency-resolved.)

程序采用显示方案实现“平均曲率运动(MCM)”的模型，解法为显示解(Program implementation by show "mean curvature motion (MCM)" model, solution for display solutions )

这是计算分维数的分形程序，经检测能完美运行，效果很好。(This is dimensions calculation fractal program, after testing can perfect operation, the effect is very good. )

遗传算法与偏最小二乘结合，应用于化学光谱的变量选择问题，希望对同学们有用。(Combination of genetic algorithm and partial least squares, used in chemical spectroscopy variable selection problem, I hope useful to the students.)

This sourcecode extracts de melcepstrum coefficient of an audio file. You should give to de function, the audio file save as a vector, and the function returns a vector with 23 melcepstrum coefficients.

振动信号预处理方法---五点滑动平均法平滑处理,matlab程序(Vibration signal preprocessing method--- five-point moving average smoothing, matlab program)

GUI，一个数字信号通过低通滤波器，可显示原信号、滤波器、目标信号的时域频域波形。(GUI, a digital signal through a low-pass filter, the original signal can be displayed, the filter, the time-domain target signal in the frequency domain waveform.)

用于读取BVH文件,可以用来提取关键帧和分割(read BVH)

PSK调制与解调都有的程序，解调过程详细，并有误码率分析(PSK modulation and demodulation are the procedures, demodulation process in detail, and a bit error rate analysis)

用周期循环检测算法检测： 首先运行a.m程序，通过此程序运算得出循环频率a值； 再运行zhouqi.m程序，对a值进行确定，通过周期循环算法对信号进行检测； (With cycle detection algorithm to detect: First run am program, through this program computing a value obtained cyclic frequency zhouqi.m then run the program, for a value determined by the cycle algorithm of signal detection )
