matlab　７．０从入门到精通　书中源代码(matlab 7.0 Mastering the book source code)

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)

Emd分解，通过峭度和相关系数选择IMF，进行信号重构，小波分解，小波包分解。(Emd decomposition, selecting IMF by kurtosis and correlation coefficient, signal reconstruction, wavelet decomposition, wavelet packet decomposition.)

牛顿-拉夫逊法在数学上是求解非线性代数方程组的有效方法，其要点是把非线性方程求解过程变成反复地对相应的线性方程进行求解的过程。(Newton- Raphson method in mathematics is an effective method for solving nonlinear algebraic equations, the point is that the non-linear equation solving process into the process repeated for the corresponding linear equation solving.)

说明：  长期演进系统，通信链路自动重传情况解析。获取是否自动重传(Long-term evolution system, automatic retransmission of communication links)

Maximum likelihood estimation for rayleigh function

Ampl for multiple programming including linear programming, nonlinear grg model

MUSIC是基于天线阵列协方差矩阵的特征分解类DOA估计算法，这里是波束空间MUSIC算法源程序。(MUSIC DOA estimation algorithm is based on the decomposition class features antenna array covariance matrix, here is the beam space MUSIC algorithm source.)

说明：  Mathieu函数工具箱，在弹性波波场分析中一个很有的工具(Mathieu Functions Toolbox v_1_0)

组合导航的程序，主要是航位推算方法的程序(Navigation procedures, mainly dead reckoning method of procedure)
