matlab锐化代码（图像锐化）

在SIMLINK中用gandner 算法实现定时环路中的时间检测(Gandner algorithm used in SIMLINK timed loop in the time of detection)

Matlab写的二维带PML边界激励源是高斯脉冲的FDTD程序(A FDTD program which is written with Matlab and have a PML and Gauss Power)

说明：  关于Lorenz函数处于混沌时的图形，包括建立Lorenz函数集画图程序(about Lorenz)

实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见，经DCT低通滤波后，图像变得很模糊。因为DCT是FFT取其实部，能量减少，因此图像变得很模糊，没有经FFT滤波后的效果好。 经DCT高通滤波后的图像： 经DCT高通滤波后，图像的低频部分被滤除掉，图像变黑，只有边缘的痕迹可见。 (The DCT of image high-pass, low pass filter and compared with the Fourier transform.)

说明：  通过比较自编MATLAB 的k-means 算法程序和SPSS 中自带的k-means聚类工具，对两个数据集聚类，并分析了聚类结果。(By comparing the k-means algorithm program of self-compiled MATLAB with the K-means clustering tool of SPSS, two data sets are clustered and the clustering results are analyzed.)

function [g, badg] = numgrad(fcn,x,varargin)

The goal of a power flow study is to obtain complete voltage angle and magnitude information for each bus in a power system for specified load and generator real power and voltage conditions.[
