利用PML 计算近场的FDTD 三维程序

二维各向异性弹性波地震波传播模拟，采用FDTD(Finite Difference Time Domain)数值模拟方法及PML(Perfect Matched Layer))和Collino混合边界，吸收下过要优于单一吸收边界。

This library defines basic operation on polynomials, and contains also 3 different roots (zeroes)-finding methods that can handle quite large polynomials (>1000 coefs) Implemented in ANSI C++ Templates. Handles all real and complex floating point types. Html doc is included.-This library defines basic operation on polynomials, and contains also 3 different roots (zeroes)-finding methods that can handle quite large polynomials (>1000 coefs) Implemented in ANSI C++ Templates.

学生的综合素质受多种因素影响,如何建立科学的评估体系是各大学多年来一直探索的问题。经 过分析各种因素建立了高校学生综合素质 模型,并对高校学生的综合素质进行科学地定性与定量分析,通 AHP 过模型计算表明:综合指数得出的结果能对学生的优点和弱点作出客观评价,有利于学生的全面发展,对当前进 行素质教育具有现实意义。-The overall quality of students affected by many factors, how to establish a scientific evaluation system of universities is to explore the issue has been. After analysis of various factors to establish a comprehensive quality model for college students and college students to carry out the comprehensive quality of qualitative and quantitative scientific analysis, Qualcomm AHP model calculations have shown that: composite index can be the result of the strengths and weaknesses of students to make objective evaluation, is conducive to the holistic development of students, carried out on the current quality of education has a practical significance.

大家请多指教-you please enlighten!

以我的近似 = INTEGRAL((F(X) DX)) 从 A 到 B： 输入： 终结点 A、 B ；整数 N。 输出： 阵列 R.（R(2,N) 是对我的近似）。 R 是由行 ； 计算只有 2 的行保存在存储中

求解矩阵的最大最小特征值及对应的特征向量，以及计算条件数-solving matrix eigenvalue largest and the smallest corresponding eigenvectors and calculate several conditions

这是我学习《数值分析》所编写的一个程序，用于线性方程组的雅可比求解。-This is my learning "Numerical Analysis" prepared by a procedure for the linear equation for the Jacobian.

非常简便，代码短且稳健性强-very simple, but short code stability-

这是用C编写的贪婪算法,非常实用,欢迎大家下载哈!-This is prepared by using C greedy algorithm is very practical, welcomed everyone to download Ha!
