说明：  实现了平方根容积卡尔曼滤波，十分好用，效果很好(This codes ultilize the srckf to filter something)

说明：  该蠕变子程序能够进行高温长时间应力下的应力应变分析以及松弛行为(The creep subroutine can be used for stress-strain analysis and relaxation behavior under high temperature and long time stress)

转载：众所周知有限元解决振动问题的能力还是有限的, 比如做齿轮啮合过程的动力学模拟就要同时涉及到接触和动力反映两个主要方面. 目前处理此类问题最成熟的软件当属MSC.ADAMS, 但ADAMS也只能在模拟过程中做到弹性与刚性接触而已! 据我所知, 已不止两位研究生试图用LS-DYNA来做此类模拟, 他们忽略了(或没搞清楚) LS-DYNA只能处理瞬态问题, 而对于该过程的模拟也是无能为力的!!! 结果是浪费了大量的时间, 甚至机会. 这本应是导师的责任, 但许多高龄导师对现代软件的不熟悉也是....那么此类问题的具体解决方案在哪里? Vibration Simulation Using Matlab and ANSYS 给出了答案. 掌握书中的内容意义非同小可! 这对于要从事CAE工作的将会受益(起码在今后20年内).随着我国经济的高速发展 解决资本积累必将是要遇到的问题, 工程(设备)维护, 系统监测也将(象发达国家)成为CAE非常重要的部分. 早早入手就能使你立于不败之地!(This book has three main purposes. The first purpose is to cc..-ct in one document the various methods of constructing and representing dynamic mechanical models. The second purpose is to help the reader develop a strong understanding of the modal analysis technique, where the total response of a system can be constructed by combinations of individual modes of vibration. The third purpose is to show how to take the results of large finite element models and reduce the size of the model (model reduction), extracting lower order state space models for use in MATLAB.)

本程序包括：DFT（离散傅里叶变换），FFT（快速傅里叶变换），IFFT（快速傅里叶逆变换），conv（卷积：圆周卷积、线性卷积），主要应用于信号处理，既可以对实序列做上述操作，也可以对复序列。(This process includes: DFT (Discrete Fourier Transform), FFT (fast Fourier transform), IFFT (inverse fast Fourier transform), conv (convolution: circular convolution, linear convolution), mainly used signal processing, either on the actual sequence to do the operation, can also be complex sequence.)

用雅可比方法求矩阵的特征值和特征向量的FORTRAN程序(Method using Jacobian matrix of eigenvalues and eigenvectors of the FORTRAN program)

FFT快速傅里叶变换，用于数字信号处理，大大提高了运行速度，节省内存开销。C语言实现(FFT fast Fourier transform for digital signal processing, greatly improving the speed and save memory overhead. C language)

求非线性系统的相平面轨迹、平衡点时，编写采用一步仿真计算状态轨线斜率的函数M文件(Phase plane trajectory of nonlinear systems, the equilibrium point, write step simulation state rail line slope function M)

说明：  多元统计分析—基于R- 数据data，讲解多元统计在R中如何实现，对于多元统计软件入门，是很实用的课程(Multivariate Statistical Analysis Based on R language .about data)

程序是关于计算两相黎曼问题的一个求解器。可以直接设置。(The code is a solver about the two-phase Riemann problem. the user can use it directly.)

大量的有限元法求解偏微分方程的实例程序，程序里有详细的解释语句(lot of finite element method PDE examples of procedures, procedures are detailed statement of explanation)
