this is some codes in systems

说明：  matlab数学手册，比较适合有基础的读者使用，适合数学分析或者数据分析(matlab mathematics manuals, more suitable for readers based on the use of mathematical analysis or data analysis for)

matlab GUI历来收到大多数学者的重视，本人编写了一些简单的GUI案例，供大家学习。(Matlab GUI has received the attention of most scholars, I write some simple GUI case, for everybody to learn.)

说明：  计算快速傅里叶变换的蝶形算法，用matlab实现的(FFT butterfly calculation algorithm implemented with matlab)

基于粒子群算法的无功优化MATLAB源代码，IEEE30节点，希望对大家有帮助(Particle swarm algorithm with reactive power optimization, more practical, we want to help, 14 nodes)

调制系数等于0.5的fsk调制与解调的matlab实现，即实现msk的调制解调(Modulation index is equal to 0.5 fsk modulation and demodulation matlab implementation, namely, the achievement msk modem )

数值分析算法-----功能:gauss-seidel迭代求解线性方程组的根 (Numerical analysis algorithms----- functions: gauss-seidel iterative root solving linear equations)

此代码为频域多通道采样实现并行传输的matlab源代码(This code for multi-channel frequency-domain sampling matlab source code for parallel transmission)

将文件扩展名改成“.m”就可以直接放在工具箱里用了 计算经验模态分解( EMD_ONLINE (On Line Empirical Mode Decomposition) computes on-line EMD IMPORTANT: EMD_ONLINE does not truly apply EMD on-line but it does AS IF. It is rather a demonstration that EMD can be applied on-line.)

对给定信号进行经验模式分解（EMD），EMD基本理论和算法可参考：何正嘉.现代信号处理及工程应用 (Do empirical mode decomposition (EMD) for a given Signal.The EMD basic theory and algorithm can refer to: He Zhengjia. Modern signal processing and engineering applications)
