关于非线性离散系统辨识，小波包分析提取振动信号中的特征频率，有小波分析的盲信号处理。( Nonlinear discrete system identification, Wavelet packet analysis to extract vibration signal characteristic frequency, There Wavelet Analysis Blind Signal Processing.)

计算重力异常,只需要输入最大重力场模型的最大阶数以及重力场模型文件名在程序里设置经纬度范围和间隔即可得到重力异常(Gravity anomaly)

说明：  神经网络算法，希望能对大家有点点帮助，可以相互交流(Neural network algorithm, I hope everyone can have little bit of help, they communicate with each other)

这是考虑了高程的面积计算公式，VB编的程序，运行即可(This is the old area of the elevation calculation formula, the program can be run VB series)

三维的FDTD实现，采用CPML边界，较为详细的注释(Three-dimensional FDTD using CPML border, more detailed notes)

经典R-K法，通过它可以计算一些简单的常微分方程的数值解(Classical RK method, which can be calculated by simple numerical solution of ordinary differential equations)

F-K域偏移法和相移法偏移程序（C语言）(FK domain migration method and the phase- shift method migration program (C language))

说明：  曲线的三次样条插值，在非首尾节点处具有三次光滑性质(Curve cubic spline interpolation, in both nodes with non-smooth nature of the three)

羊与狼的故事...主要实现狼进入若干羊圈后，寻找最后所有羊圈中剩余的狼和眼数目( the wolf and sheep)

本程序包括：DFT（离散傅里叶变换），FFT（快速傅里叶变换），IFFT（快速傅里叶逆变换），conv（卷积：圆周卷积、线性卷积），主要应用于信号处理，既可以对实序列做上述操作，也可以对复序列。(This process includes: DFT (Discrete Fourier Transform), FFT (fast Fourier transform), IFFT (inverse fast Fourier transform), conv (convolution: circular convolution, linear convolution), mainly used signal processing, either on the actual sequence to do the operation, can also be complex sequence.)
