求解声学问题的边界元程序，给声学研究的人员很大启发(Solving the problem of acoustic boundary element program, to inspire great acoustic research staff)

c++算法源代码，主要是POJ上面的算法，根据标号可以找到。(c++ algorithm source code, POJ above algorithm, based on the label can be found.)

说明：  一个用C语言编写的求混沌序列的源程序,挺好的!(a C language for the chaotic sequence of the source, very good!)

基于混沌理论进行数据预测的程序，欢欢迎需要的朋友参考下载，并提出修改意见 (, Please feel welcome the reference to a friend download data to predict the process based on chaos theory, and suggest modifications)

计算牛顿和拉格朗日插值方法,用户输入插值结点(calculated Newton and Lagrange interpolation methods, user input interpolation nodes)

C++实现的FFT，详细，简单，内含多个测试类(using C++ implements fft，including serials class)

计算半方差，如果按克里金法计算插值要求计算半方差，用此程序可实现。(Calculation of semi-variance, if the Kriging interpolation method call for the calculation of semi-variance, using this procedure can be realized.)

灰色关联度分析是基于灰色系统的灰色过程, 进行因素间时间序列的比较来确定哪些是影响大的主导因素, 是一种动态过程的研究。(Grey Relational Analysis is based on gray gray process, the comparison of the time series between the factors to determine what affect the the big dominant factor, is a dynamic process.)
