基于matlab的optical flow calculation(Matlab-based optical flow calculation)

文件是QAM调制的matlab程序。包含星座图以及误码率/信噪比图。(File is QAM modulation matlab program. Contains the constellation diagram and BER/SNR map.)

Digital watermarking

This is an matlab source code for smoothed particle hydrodynamic simulaiton. It include matlab routines and input data.

说明：  MATLAB，传输矩阵法，仿真光纤光栅温度特性，主要反映不同温度下反射峰的漂移现象(MATLAB，Fiber Bragg Grating Temperature characteristics)

共散射点正演模拟，而且有P波和S波速度扫描和速度谱制作的程序。(Forward modeling of scattering centers, and a P-wave and S-wave velocity and velocity spectra produced by the scanning process.)

this program simulates 1D electromagnetic Maxwell equations with absorbing boundary condition to prevent reflection from the boundaries of the problem space. this is by using finite difference time domain method FDTD

Matlab code for doing seismic semblance

matlab的工具，常用的工具，非常有用的(matlab tools, commonly used tools, very useful)

根据频率的不同，设置不同的滤波器，包括低通、高通、带通等(Depending on the frequency set different filters, including low pass, high pass, band pass, etc.)
