地球科学（Fortran90）: 计算空间重力异常、扰动重力、垂线偏差或重力梯度的垂向梯度。 计算方式：数值积分、二维平面FFT、二维球面FFT或一维FFT。(Earth Science (Fortran90): calculate the gravity anomaly, gravity disturbance, the deflection of the vertical or gravity gradient vertical gradient. Calculation: numerical integration, FFT of the two-dimensional plane, two-dimensional spherical FFT or one-dimensional FFT.)

优化设计算法：用powell法求解目标函数的最优解和最优值，已经验证算法的正确性，在visual c++6.0下开发(Optimization algorithm: Solving the objective function with powell optimal solution and optimal value, has verified the correctness of the algorithm, the visual c++6.0 under development)

Fortran 95程序设计【彭国伦】第7章原代码，非常有学习价值！(Fortran 95 programming [Lun Peng-- Chapter 7 of the original code, the very value of learning!)

这个程序是关于轴承刚度方程的MATLAB程序(This program is about the bearing stiffness equation MATLAB program)

计算按频率抽取的基4快速傅里叶变换算法，与基2FFT相比，基4FFT的乘法量约减少25 。(Calculating frequency taken by fast Fourier transform algorithm base 4, compared with the base 2FFT the base 4FFT multiplication about 25 less.)

c++运算符程序编写运用，包括+，-，*，/，>>,<<(c++ operator programming use, including+,-,*, /, > > , < < )

此程序用最小二乘法拟合椭圆图像，模拟地球的形状(This program fit ellipse images using the least squares method to simulate the Earth' s shape)

用于matlab环境下的支持向量机svm的工具箱，做这方面的朋友很需要哦(Matlab environment for support vector machine SVM Toolbox, make this area really need a friend Oh)

通过C++头文件实现的有限元形状函数计算程序(finite element shape function)
