说明：  地球处理多边体的重磁异常的正演，主要是地球数据处理的课程的实验项目2(The forward modeling of gravity and magnetic anomalies in the earth s processing of the multilateral body is mainly the experimental project of the earth data processing course 2)

MFC编写的计算器，基本功能都已实现，加速键没有实现(Written in MFC calculator, basic functions have been achieved, not achieved accelerator)

抛物方程是由赫姆霍兹方程推导而来，在计算大区域电磁传播有较大的优势，本程序是二维的情况。(Parabolic equation is derived the Herm Holtz equation, in the calculation of large areas of electromagnetic propagation has a greater advantage, the program is a two-dimensional situation.)

很好用的有关矩阵的各种操作，包括求逆，特征值，特征向量，svd分解等(good part of the matrix of various operations including inverse, eigenvalues, eigenvectors, svd decomposition, etc.)

C++中矩阵运算的实现 nr3.h为其他的书籍代码，测试环境为VS2008(Achieve C++ in matrix operations nr3 code for other books)

MFC做的计算器程序，可以实现加减乘除。平方，立方等功能(MFC to do calculator program can be achieved subtraction multiplication and division. Square, cubic and other functions)

一维的N_S方程的求解程序，是计算流体力学的算例(the N_S equation of one dimension .)

LS_SVM 偏最小二乘结合支持向量机(The LS SVM partial least squares and Support Vector Machine)

Fractional knapsack problem, Greedy algorithm

录音程序，音频录音fft程序，并加界面显示(radio record code)
