小波变换已应用到工程的各个方面，但一般只是应用MATLAB的小波工具包来编程，有时需要自己编程实现，故这里给出了DB4小波变换的C实现(Wavelet transform has been applied to all aspects of the project, but generally only apply MATLAB wavelet toolkit for programming, sometimes need their own programming, so here is a DB4 wavelet transform C implementation)

33节点的配电网重构程序，基于粒子群算法。相当快速。但是需要再修改源码才可以重新生成数据。(33 node distribution network reconfiguration procedures, based on particle swarm optimization. Pretty fast. But the need to modify the source code before they can re-generate the data.)

说明：   数据挖掘的重要算法SVM的实现,用matlab(important data mining algorithms to achieve SVM using Matlab)

说明：  用DFT计算连续信号的谱 通过应用 DFT 进一步加深对离散信号 DTFT 和 DFT 的概念及其相互关 系的理解。 =利用 DFT 计算连续周期信号的频谱(DFT calculations using a continuous signal by applying the DFT spectrum of discrete signals to further deepen the concept of DTFT and DFT and their mutual understanding of the relationship. = DFT calculations using a continuous spectrum of periodic signals)

说明：  该MATLAB程序用遗传算法GA处理最短巡航路径问题（TSP）(The algorithm uses GA to deal with the shortest load （TSP）)

说明：  混合Newton发求最小值.原理是基于Newton法，求解非线性方程。利用和最速下降法混合，避免了Newton的不足(ues mix Newton method to solve the problem: min f(x))

Mtlab function for PCA

to find the discrete fourier transform using the fast fourier algorithm, any sequence of lengths which are multiples of 2 simply append zeros to satisfy this requirement

The number π is a mathematical constant that is the ratio of a circle s circumference to its diameter and is approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes romanized as "pi
