It is a FDTD program which produce Black-Man-Harris Source in free space.

使用神经网络实现对函数sin(x1)/x1*sin(x2)/x2的模拟，代码为matlab代码，输入为二维数组，输出为一个数，结果误差为0.225左右,(Using neural networks to function sin (x1) Analog/x1* sin (x2)/x2, the code for matlab code, enter a two-dimensional array, the output is a number, the result error is about 0.225,)

应该已经非常优化的floyd程序。简短、运行时间短、简单易理解。初学者亦可理解。实现任意两点间的最小距离和路径(Floyd should have a very optimized program. Short run time is short, simple and easy to understand. Beginners can understand. To achieve the minimum distance between any two points and path)

MATLAB中MEX命令的两个程序例子, 有详细解释, 如何在MATLAB里面调用C/C++函数(MATLAB MEX orders of the two procedures example, a detailed explanation How MATLAB inside called C/C function)

均匀介质二维声波数值模拟，采用cerjan边界条件，有公式及参考文献。带有速度模型以及雷克子波函数，解压后直接运行就可以(The homogeneous medium two-dimensional acoustic wave numerical simulation, boundary conditions of cerjan, and formulas and references. With the velocity model and the the Ricker wave function, and can run directly after decompression)

matlab的常用函数速查，包括了大部分常用函数，用ctrl+f就可以直接查找。(including matlab commonly used functions, including the most commonly used functions, you can search the functions using ctrl+f .)

可以直接画出lorenz系统在各种参数下的3D演化吸引子和分叉图(Can directly draw the evolution of the the lorenz system in the various parameters of the 3D attractor bifurcation diagram)

THIS CODEIS USEFUL FOR COMPRESSION OF DATA USING BITMASK AND RLE

大学数值分析算法，重要参数的提取，采用的是脉冲对消法，基于kaiser窗的双谱线插值FFT谐波分析，可以动态调节运行环境的参数，三相光伏逆变并网的仿真，相关分析过程的matlab方法，结合PCA的尺度不变特征变换(SIFT)算法。( University of numerical analysis algorithms, Extract important parameters, It uses a pulse of consumer law, Dual-line interpolation FFT harmonic analysis kaiser windows, Can dynamically adjust the parameters of the operating environment, Three-phase photovoltaic inverter and network simulation, Correlation analysis process matlab method, Combined with PCA scale invariant feature transform (SIFT) algorithm.)
