convolutional code,create a matlab conde using in channel coding

this is simple sample of Hopfield neural network main file: Hopfield.m

说明：  本文使用了两种方法优化matlab的程序，缩短了算法的时间。方法1：使用Optimization Toolbox中的并行优化；不需要修改代码。方法2：增加一行代码，即可优化(Improving Optimization Performance with Parallel Computing)

RGB图像格式转换为YUV格式。 根据RGB到YUV关系转化以及分量取平均值转换两种方法，以实例形式编程，不是子函数的形式。(RGB to YUV。 figure s style transform.)

这是MATLAB书中的完整的示例代码，是学习的很好的参考(This is a complete example of MATLAB book code, is a good reference to learn)

在matlab平台上使用SVM对iris数据集进行分类(use SVM Classification of Iris data set in matlab)

说明：  多通道和单通道接收到的北斗信号数据，利用接收到的北斗数据（.dat .txt文件），进行解析，得到初始伪距，平滑伪距，载波相位，并计算其标准差，并画图。(The Beidou signal data received by multi-channel and single channel are analyzed by using the Beidou data (. Dat. TXT file). The initial pseudo range, smooth pseudo range and carrier phase are obtained, and the standard deviation is calculated and plotted.)

对原有数据进行排列，找到它所在位置，求出符合要求的最小值(The original data are arranged in a position to find it, find the minimum to meet the requirements)

神经网络迭代法，数据量不大，用于图像压缩(Neural network iteration method, the data volume is not large, used for image compression)

说明：  MATLABC基础学习，GUI编程，降噪，图像处理-去噪、压缩（Matlab GUI）(MATLABC basic learning, GUI programming, noise reduction, image processing-denoising, compression (Matlab GUI))
