说明：  为了减少边缘检测中的噪声影响,设计了一种分数阶差分滤波器,给出了该滤波器的原理,分析了此类滤波器的幅频特性.(In order to reduce the effect of the noise in edge detection,a kind of fractional-order difference filters were designed,whose theory was worked out and amplitude-frequency characteristic were analyzed.)

This does convolution of two sequences in stepwise manner according to normal understanding. sigfold.m:-fips signal 1..and changes n accordingly. sigshift.m:-shifts flipped signal from left to right to cover all overlapping sigmulti.m:-multiplies two signals at each instant of overlapping convolution.m:-it finally calculates the sum of the product

pq control of pv to grid

One of the most advanced routines in picture editing. Remove undesirable parts from pictures.

打开Matlab，在工作窗口中输入程序，运行；出结果(Open Matlab, the working window, type the program, run results)

k-l变换在matlab下的源代码，非常实用。(K-L transformation in matlab， which is so easy to apply to many situations.)

dpxm simulink仿真 模块建立 波形分析(dpxm Simulink simulation)

主要用于广义回归模型，比如二项分布以及普松分布等(generalized regression)

基于matlab语言的抗震工程分析，里面很多代码值得学习。(Matlab language-based seismic engineering analysis, which a lot of code is worth studying.)

这是一个交流变直流的仿真，实现了直流的稳定输出，并且有较高的功率因数( This is a simulation of the AC to DC, DC to achieve a stable output, and a higher power factor)
