程序

信息是个很抽象的概念，本文介绍了熵的概念，并介绍计算方法(information is a very abstract concept, this paper introduces the concept of entropy, and the calculation method introduced)

此程序碼為計算inverse-preisach之解析法計算(This program code for calculating inverse-preisach of analytical method)

包括牛顿法，阻尼牛顿法，变尺度算法，最速下降法的优化算法程序。(Newton' s method, damped Newton method, variable metric algorithm, the steepest descent method optimization algorithm.)

基于模式耦合方法建立三维面波传播模型，该代码对于做波场模拟的同学很有用。(This program calculates the wavefield produced by a monochromatic surface wave mode incoming on a 3D cartesian structure. It is based on mode coupling and multiple scattering.)

潮流调和分析程序，非常实用，里面有说明文件，基本原理是采用最小二乘法来求解超定矩阵，各种参数用来控制选择分潮，间隔时间等。(harmonic analysis)

考虑地球J2项摄动的轨道积分器，变步长，基于龙格库塔78阶，(orbital integrator considering the J2 pertubation, based on the Runge-Kutta 78 integrator, use automatic step control)

三次样条插值（简称Spline插值）是通过一系列形值点的一条光滑曲线，数学上通过求解三弯矩方程组得出曲线函数组的过程。本函数中采用第一类边界值(Cubic spline interpolation (referred Spline interpolation) through a series of key points of a smooth curve, mathematically by solving the three-moment equations derived curve function group process. This function uses the first boundary value)
