repeated-measures-ANOVA

说明：  用于abaqus二次开发材料VUMAT，为初级学者找到更简单的方法(Materials for ABAQUS secondary development)

说明：  二阶曲线拟合，最小二乘法，此程序是在c++ builder6.0环境下开发的(second curve fitting, least squares method, this procedure is in c builder6.0 development of the environment)

数值分析里面的：不动点迭代法、牛顿迭代法、共轭梯度法和最速下降法(Conjugate Gradient)

用C语言程序通过先随机选取K个对象作为初始的聚类中心。然后计算每个对象与各个种子聚类中心之间的距离，把每个对象分配给距离它最近的聚类中心。聚类中心以及分配给它们的对象就代表一个聚类。一旦全部对象都被分配了，每个聚类的聚类中心会根据聚类中现有的对象被重新计算。(C Programming Language by first randomly selected the K object as initial cluster centers. And then calculate the distance between each object and each seed cluster center, and assign each object to its nearest cluster center. Cluster centers, and the object assigned to them on behalf of a clustering. Once all the objects are assigned to each cluster cluster centers will be based on the existing object clustering is recalculated.)

用MRT-LBM计算顶盖驱动流的程序，比LBGK方法更加稳定。(Codes for lid-driven flow with MRT-LBM, which is more stable than LBGK.)

一种流形学习算法，用于非线性降维，文章发表在2000年science杂志上，是一种非常经典的算法。(A manifold learning algorithm for nonlinear dimensionality reduction, articles published in science journal in 2000, is a very classic algorithms.)

粒子滤波PF，无迹粒子滤波UPF，卡尔曼滤波KF，扩展卡尔曼滤波EKF等例程与比较。建议下载，清晰明了(Particle filter PF, Untraced particle filter UPF, Kalman filter KF, extended Kalman filter EKF and other routines and comparisons.)

数值模拟方腔内Rayleigh-Benard对流。采用交错网格投影法，能量方程采用松耦合方法。(Numerical Simulation of square cavity Rayleigh-Benard convection. Using staggered grid projection method, the energy equation using loosely coupled approach.)

和大家分享一个全相位FFT，matlab程序，程序中全相位fft实现方法有两种，注释掉的根据原理推到得来，自己看吧。(And share a full-phase FFT, matlab program, the program fft implementation in all phase two, comment out the basis of the principle pushed to come, see for yourself.)

利用ANSYS有限元仿真软件对复合材料进行异常检测仿真实验，程序为一损伤样板模型(ANSYS finite element simulation software for composites simulation anomaly detection, the program is a damage model model)
