qpsk系统仿真过程，包括输入和输出,值得参考(qpsk system using input and output)

此代码是利用 MATLAB 工具设计的一个指纹数字图像识别系统的关键代码(fingerprint identification)

PSAT包含了：PF-潮流计算；CPF-连续潮流；OPF-最优潮流；SSSA-小扰动分析；TDS-时域仿真；GUI-用户人机界面；GNE-自定义模型等功能。该工具包已经可以计算上千节点规模的系统。而且该软件包源代码完全公开，因此用户可以根据自己的研究兴趣编写修改相应源代码实现研究目的。(PSAT includes: PF-flow calculation CPF-continuous fashion OPF-OPF SSSA-small perturbation analysis TDS-time domain simulation GUI-user machine interface GNE-custom models and other functions. The kit can have thousands of computing nodes scale systems. And the package source code is completely open, so that the user can modify the source code to write research purposes according to their research interests.)

扩展卡尔曼滤波在跟踪运动轨迹中的应用（matlab程序）(Extended Kalman filter (EKF) simulation demo)

使用先对图像进行灰度变换，中值滤波处理，然后使用各种微分算子，比较不同处理效果(Use the first gray-scale transformation of the image, median filter processing, and then use a variety of differential operators, compare effects of different treatments)

主成分分析Matlab源码分析程序可以实现希望能帮助大家(Principal Component Analysis Matlab source code analysis program can achieve hope to help everyone)
