Butterworth-hpf

说明：  这是《matlab小波分析》教材上的第一章程序（例）的源码，希望分享！(This is the &quot matlab wavelet analysis&quot textbook chapter on the procedure (cases) of the source, I hope to share!)

描述了一个用matlab描述的卡尔曼滤波实现的例子，可以直接运行观察结果，对kalman滤波的学习有很好的借鉴作用(Describes a Kalman filter is described by matlab examples of implementation can be run directly observe the results of the kalman filter has a good reference for learning)

这段程序是关于图像分析中的各种颜色处理的，感兴趣的同学可以看看(This program is all about the color of the image analysis processing, interested students can look)

This program basically count every character that is in a text. The program opens de text an reads it, stores data in a matrix and count characters that are in Ascii code and writes the results in a new text file

matlab平台下libsvm程序包进行模式分类(libsvm in matlab to pattern classification)

matlab code for Three-Phase AC-DC-AC PWM Converter

变刚度单元有限元计算的单元刚度矩阵和等效结点荷载矩阵(The finite element calculation of variable stiffness element stiffness matrix and equivalent nodal load matrix)

在MATLAB下运行后可以得到一个日历界面，并且有时间显示！(Run in MATLAB can interface with a calendar and time display!)

说明：  进行Gray码的图像变化，思想是进行位操作，首先将原始图先的每一位取出来， 然后将十进制转化位二进制，将其按位取出，进行变换，得到变换后图像的每一位的值，再进行组合即可(Gray code for the image change idea is to place operation, first the original plan to take out each and every first and then bit binary decimal conversion, be removed by bit, for transformation, transformed the image of each of value, then the combination can be)
