主要是数字信号中窗函数的设计与分析，matlab源代码的设计，提供了时域与频域分析(Is mainly the design and analysis of window function in the digital signal, the design of Matlab source code, provides the analysis of time domain and frequency domain)

举例实现由int转换到char类型；string数据连接添加char数组；string转化到const char类型；(Example to achieve the conversion from int to char type string data connections add char array string conversion to const char type )

说明：  可就在三个错误的bch码，以及经过仿真在不同SNR下的误码率曲线。我们的业余作业。经过调试的。(This is my homework on 3-error-correcting bch code and its bit error rate curves at different SNR after debugging.)

用matlab画了一个小动物，利用了plot，sina，cos等 函数(use Matlab drew a small animal )

卡尔曼滤波不错的程序，很实用，大家好好研究一起分享一起进步吧(Kalman filtering good program, very practical, we make good progress in research to share with the Bar)

说明：  粒子群优化算法计算出的PSS优化模型，为四机两区模型(PSS optimization model calculated by particle swarm optimization algorithm)

matlab 信号处理工具箱，信号系统模型，线性非线性模型(matlab signal-processing-toolbox)

有限单元，稀疏矩陈存储。 有限单元程序组件。 开发：东华理工大学 联系：张志勇(Finite element, sparse moments Chen storage. Finite element program components. Development: Tung Wah Group of Hong Kong Polytechnic University Contact: Zhang Zhiyong)

模仿微信打飞机 的Demo 无bug 希望大家一起学习

三次样条插值，拉格朗日，分段线性插值的matlab程序(Cubic spline, the piecewise function interpolation method and Lagrangian matlab program, for example)
