fft傅里叶快速变化程序，里面说的很清楚，很使用。(FFT Fourier rapid change program, which made it very clear, is to use. )

一些简单的UDF文件，实现流场中梯度和某一点压力的检测提取(Some UDF profiles)

fortran程序，计算应力强度因子和特征值和特征向量，研究多种材料接触(fortran program)

fortran code for LINEAR_WAVE PROPAGATION by forward time forward spase method.

静力缩聚法求缩聚后的结构刚度、质量矩阵，以及频率(Static condensation method for structural stiffness after condensation, mass matrix, and the frequency)

说明：  矩阵计算英文版第4版，经典，经典，很不错！！！！！请下载！！！！！！(Matrix Computing English Version 4, classic, classic, very good!!!! Please download!!!!!!)

短时傅立叶变换及其反变换---绝对可运行！(Short-time Fourier transform and its inverse transform- absolutely can run!)

说明：  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)

对离散点进行多项式拟合，不同于传统多项式拟合高次出现病态，此程序可以拟合高阶多项式( ORTHOFIT Fit polynomial to data. YS = ORTHOFIT(X,Y,N) smooths/fits data Y(X) in a least-squares sense using a polynomial of degree N and returns the smoothed data YS.)
