pitch detection with correlation

说明：  金庸代表作，非常的吸引人，情节生动富有煽动力(good)

50 HZ to 150 HZ transformer by using saturation reactor

从曲线中检测到其峰值：先利用二次求导得到所有凸点，设置门限，去除过低的凸点，然后利用滑动窗的方法，在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

该书系统地介绍了matlab在小波分析中使用方法，简单地介绍了小波分析的原理，及采用matlab如何实现小波分析!(The book systematically introduces matlab in the use of wavelet analysis method, a simple introduction to wavelet analysis theory, and the use of wavelet analysis matlab how to achieve!)

Solving beam problem

Cutting and deflection in beam

该函数使用快速傅里叶变换FFT计算序列平均周期(This function uses the fast Fourier transform (FFT) calculation of the average cycle sequence)

说明：  matlab 经典算法包括很多非常经典的matlab算法。值得一看。(matlab classical algorithms, including many classic matlab algorithm. Worth a visit.)

图论中的floyd算法。简单的小程序，可以插入任何过程中，方便实用。(In graph theory algorithms. Simple procedure, you can insert any process, convenient and practical.)
