color-difference

群智能算法中的差分算法，好用有效，含有测试函数和换图函数(differential algorithm)

说明：  生成调制信号数据集 信号集包括2ASK，2PSK，2FSK，4ASK，4PSK，4FSK，8ASK，8PSK，8FSK，16QAM，64QAM，信号比范围-20db至18dB，调制到中频。 信号参数 符号率fb：1e3 载波频率fc：2e3 采样频率fs：64e3 信号频道：awgn，rayleigh(Generating Modulation Signal Data Set Signal sets include 2ASK, 2PSK, 2FSK, 4ASK, 4PSK, 4FSK, 8ASK, 8PSK, 8FSK, 16QAM, 64QAM, signal ratio range - 20 dB to 18dB, modulated to intermediate frequency.)

运用Sobel算子对图像进行锐化的源代码(Using Sobel operator to sharpen the image source code)

These set of programs are written to design a robust power system stabilizer for minimizing the effects of low frequency oscillations in electric power systems. A complete nonlinear model of the power system represented by a single machine connected to an infinite bus is developed in the Simulink environment. A fuzzy Power System Stabilizer is designed using the fuzzy logic toolbox of matlab and its parameters are tuned by a NEural Network controller.

compute the LU decomposition for the matrix A

图片印刷字符的识别（可识别多种字体） 将Matlab工作空间路径设置为本文件夹 在Matlab命令窗口内输入： numCongnition( able1/01.jpg ) 通过改图片来对不同的图进行处理，其中able1,able2,able3三个文件夹分别对应三种字体 命令窗口输出要识别的字符，并且自动弹出中间处理过程窗口 也可以运行： num = pretreat( able1/01.jpg ) imshow(num) 直接得到预处理后的图片 再键入： getNumber(num) 得到字符输出 (Set the Matlab workspace path to this folder In the Matlab command window input: NumCongnition ( able1/01. JPG) Through change pictures to deal with different figure, including able1, able2, able3 three folders corresponding to three kinds of fonts Command window output to identify characters, and automatically process among popup Windows Can run: Num = pretreat ( able1/01. JPG) Imshow (num) Directly after preprocessing of images Type: GetNumber (num) Get the output character)

This is the matlab source codes. It will generate the unit step sequnce and unit impulse sequence.

说明：  我ANN的大作业，里面有三个程序，里面有测试训练数据主要关于MLP(ANN big operation, there are three procedures, and they test data on the training MLP)

偏微分方程有限元的数值解的matlab程序，具有较好的实用性，方便大家使用和参考。(Partial differential equations finite element numerical solution matlab program, with good usability, to facilitate the use and reference.)
