This programe hides secret data inside a carrier file using LSB technique. This is example of Steganography

说明：  判别分析的matlab源代码，文件中有三种方法，每种方法都有测试数据(Discriminant analysis matlab source code, documentation there are three methods, each method has the test data)

GPOPS是一个可以进行大规模非线性优化的MATLAB工具箱.(GPOPS, short for General Pseudospectral OPtimal Control Software is a Matlab optimal control software designed to implement the Gauss and Radau hp-adaptive pseudospectral methods. These methods approximate the state using a basis of Lagrange polynomials and collocate the dynamics at either the Legendre-Gauss or Legendre-Gauss-Radau points. )

基于快速模拟退火反演算法采用地震数据反演反射系数，进而可以很好地预测出弹性参数。(Based on fast simulated annealing inversion algorithm using seismic data inversion reflection coefficient, which can well predict the elastic parameters. )
