非常不错的fft的算法，在tc2.0环境下编译通过了的-very good fft algorithm in tc2.0 environment through its compiler

应用背景JPHide 和JPSeek 的源代码！JPHide&JPSeek是一个JPEG图像的信息隐藏软件！-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e

此程序用来求取反射系数。通过左普利兹方程组，知道反射角，给出两层水平地层的横波速度，纵波速度，以及两层的密度，即可来求取反射系数，透射系数。超过临界角时候，使用虚数，并取模作为最终结果。此程序可用来进行地球物理中，反射波，投射波能量、振幅的求取。

求解Fibonacc数列中大于t的最小的一个数，结果由函数返回-Solving Fibonacc series in t is greater than the smallest number of results by the function returns

将求解偏微分方程和局部网格加密简单组合在了一起。用的方程是一个含有间断二次系数的椭圆型方程，在系数间断的位置，解会有一个弱间断。-Will solve the partial differential equations and local mesh refinement simple combinations together. Used equation is a quadratic coefficient of containing discontinuous elliptic equations, the location of discontinuity in the coefficient, there will be a weak solution of continuity.
