音乐教学论文，主要介绍了音乐教学方面的一些技巧。(Music education papers, introduces some of the music teaching skills.)

非线性动力系统中分叉图用来定性的表示系统行为的演化，本代码中ode1.m定义了一个经典的Lorenz系统，sode3.m对该系统计算并画出了参数敏感区的分叉图。(Nonlinear dynamic system bifurcation diagram used to express qualitative evolution of system behavior, the code defines a ode1.m classical Lorenz system, sode3.m of the system to calculate and draw the sensitive areas of the bifurcation parameter Fig.)

很好用的LightGBM，需要set和mex(Good LightGBM, set and mex)

直接将秘密图像的高4bit隐藏在RGB载体图像的R,G,B层中所选的那一层的低4bit,并将秘密图像提取出来，最后显示。要求载体图像的大小大于等于秘密图像的大小，且秘密图像是二值或灰度图像(Directly to the secret image hidden in the high-4bit RGB vector images R, G, B layer, then a layer of selected low 4bit, and extracted secret image, the final show. Required size of the image carrier is greater than equal to the size of the secret image, and the secret image is a binary or gray image)

生成进制数为4，调制指数为1的4CPFSK信号(Generate a hexadecimal number is 4, the modulation index for 1 4CPFSK signal)

EKF-SLAM Simulator This version of the simulator uses global variables for all large objects, such as the state covariance matrix. While bad programming practice, it is a necessary evil for MatLab efficiency, as MatLab has no facility to avoid gratuitous memory allocation and copying when passing (and modifying) variables between functions. With this concession, effort has been made to keep the code as clean and modular as possible.

主要根据一个简单的电网潮流计算实例，来说明潮流计算的具体步骤，以及计算过程中出现的一些问题(Mainly based on a simple power flow calculation examples to illustrate the specific steps flow calculation, and calculation of some of the problems arising in the course)
