该源代码是本人亲自所写，使用DWT对图像可以进行三次小波分解，直接下载可以使用，对图形图像处的同行们非常有用，欢迎下载。(The source code is written by himself, the use of DWT can be three times the image wavelet decomposition, a direct download can be used in the graphic image Department colleagues very useful are welcome to download.)

说明：  利用IIR滤波器设计一个低通滤波器，能够分析到电力系统中的三次谐波，要求满足如下指标：截止频率150HZ，阻带衰减≥30db(IIR filter design using a low-pass filter, to analyze the power system in the third harmonic, the requirements to meet the following indicators: cut-off frequency 150HZ, stopband attenuation ≥ 30db)

这是一个人脸识别的matlab例程，可以运行(here is an example of facerecognize)

This is a program of a diversity transmission system based on superposition modulation

说明：  计算在一个矩形里，用同等大小圆来覆盖这个区域，所需要的最小圆个数，我已经运行过(Calculated in a rectangle, the circle with the same size to cover the region, the minimum required for a round number, I have to run-off)

巴特沃特带阻滤波器的设计，返回分子分母多项式系数，还可以作出增益曲线，以及求出相位响应以及群延时响应(Batewote band stop filter design, the return of molecular denominator polynomial coefficients, can gain curve, and the calculated phase response and group delay response)
