一篇蛮好的文章，关于MATLAB的仿真和实例说明，包括一些simulink里面的模块说明(A fine article on the MATLAB simulation and examples, including some inside the module that simulink)

说明：  原理：以待处理的像素作为中心，取一个nXn的模板，在模板中选择k个与待处理像素的值最接近的像素，将这k个像素的均值替换原来的像素值。 假设n=3，k=5，调用方法：b = KNNMeanFilter(a, 3, 5)(Principle: to be treated as the center pixel, take a nXn template select the template and the pending k-nearest pixel values of pixels, this k pixels mean replacing the original pixel value. Assuming n = 3, k = 5, call the method: b = KNNMeanFilter (a, 3, 5))

提供了小波算法的程序，该程序在MATLAB中得到验证，简单可行。(introduce a program about the wavelet ,the program is easy and used in the MATLAB)

this code is to sample the signal

【kongjian_jiase.m】：MATLAB对excel文件的每行最大值或最小值标以字体颜色和背景颜色设置，m文件可以让大家了解matlab的控件函数用法。好资料喔。([Kongjian_jiase.m]: MATLAB excel file for each row in the maximum or minimum standard font color and background color settings, m files can let everyone know matlab control function usage. Oh good information.)
