说明：  Neville插值算法，xa为自变量数组，xy为因变量数组；x为待插值的自变量(Neville interpolation algorithm, xa array as variables, xy array as the dependent variable x for the independent variables to be interpolated)

包络线去除完全用Excel函数写的包络线去除分析，仅实现了1850—2100nm的包络线去除，其他波段可自行扩展(Continuum Removal MATLAB Compiler 1. Prerequisites for Deployment . Verify the MATLAB Compiler Runtime (MCR) is installed and ensure you have installed version 7.13. . If the MCR is not installed, run MCRInstaller, located in: <mcr_root>* oolboxcompilerdeploywin32MCRInstaller.exe For more information on the MCR Installer, see the MATLAB Compiler documentation.)

二层地质模型波场模拟,用有限差分进行波场的模拟,充分利用多波多分量地震记录，以及各向异性方面的独特信息，可有效地减少 纵波勘探的多解性，定量地描述裂缝储层，改善某些纵波资料成像不好地区的构造 成像。这样可获得比纵波分辨率高的多波剖面，从而有利于研究小幅度构造、断层、 裂缝裂隙等复杂地质现象，对油气勘探与开发具有现实意义和实用价值(Two-layer geological model wave field simulation, using finite difference wave field simulation to make full use of multi-wave multi-component seismic records, and the anisotropy of the unique information can be effective in reducing the P-wave exploration, multi-solution and quantitatively describe the crack reservoir to improve the poor image of some P-wave data area structure imaging. This availability of higher resolution than the longitudinal wave of multi-wave profile, thus contributing to the small amplitude structures, faults, cracks, fissures and other complex geological phenomena, for oil and gas exploration and development of practical significance and practical value)

这是python一个数学计算库，非常有用，而且python在处理科学计算时经常会用到它(This is a mathematical calculation python library is very useful, but when dealing with scientific computing python often use it)

进行干扰源以及声源定位的时延估计技术，以及定位迭代算法(Sources of interference and delay estimation techniques for sound source localization, as well as positioning iterative algorithm)

《电子战信号处理》讲义 ，西电赵国庆老师的经典讲义，学习电子战信号处理的童鞋一定要看看哈(Electronic Warfare Signal Processing)

说明：  任意给定一个M进制的数X，利用栈实现数值转换。(Given an arbitrary number of M band X, use the stack to achieve numerical conversion.)

数学最优问题中，拉格朗日乘数法（以数学家约瑟夫·路易斯·拉格朗日命名）是一种寻找变量受一个或多个条件所限制的多元函数的极值的方法。(In the mathematical optimization problem, the Lagrange multiplier method (named by the mathematician Joseph Luis Lagrange) is a method of finding the extremum of a multivariate function which is restricted by one or more conditions.)
