灰度拉伸的小仿真，用了多种尝试，希望对大家有帮助(simulation of Gray stretch, i hope it is usefull to you.)

此代码应用于将xml文件转换为mat文件。在图像的目标识别时我们需要获得一些图像的点坐标。但是通过label me。我们只能获得xml文件的形式，这样我们就需要将xml文件转换为mat文件。方便在matlab的语言环境中进行处理(This code is used in the xml file into mat file. When the target image recognition we need at some point in image coordinates. But by label me. We can only get in the form of xml files, so we need to convert the file to mat xml file. Facilitate processing matlab language environment)

相参脉冲串复调制信号，包括随机梯度算法，相对梯度算法，ldpc码的编解码实现。( Complex modulation coherent pulse train signal, Including stochastic gradient algorithm, the relative gradient algorithm, Codec ldpc code implementatio.)

脉冲响应的相关分析算法并检验，滤波求和方式实现宽带波束形成，线性调频脉冲压缩的Matlab程序。( Related impulse response analysis algorithm and inspection, Filtering summation way broadband beamforming, LFM pulse compression of the Matlab program.)

三电平变流器的空间矢量调制算法的m文件，输入为三相电压电流和母线电压。输出为比较寄存器的值。(M files of the three-level inverter space vector modulation algorithm, the input to the three-phase voltage and current and bus voltage. Output compare register value.)

光顺MATLAB中画出的曲线，相当于Excel中的拟合曲线的功能(Fairing draw curves in MATLAB)

数据模型归一化，模态振动，采用加权网络中节点强度和权重都是幂率分布的模型，GSM中GMSK调制信号的产生，实现了对10个数字音的识别，感应双馈发电机系统的仿真。( Normalized data model, modal vibration, Using weighted model nodes in the network strength and weight are power law distribution, GSM is GMSK modulation signal generation, To achieve the recognition of 10 digital sound, Simulation of doubly fed induction generator system.)

this book will help to get knowledge about digital design very deeply
