KIVA 3V的入门介绍

FFT（Fast Fourier Transformation）是离散傅氏变换（DFT）的快速算法 [1] 。即为快速傅氏变换。它是根据离散傅氏变换的奇、偶、虚、实等特性，对离散傅立叶变换的算法进行改进获得的。(FFT (Fast Fourier Transform) is a fast algorithm of discrete Fourier Transform (DFT). That is fast Fourier transform. According to the odd, even, imaginary and real characteristics of discrete Fourier transform, the algorithm of discrete Fourier transform is improved.)

这是一个三次样条插值函数实现的C代码。如果插值点需要改变，可以在程序中改定。(This is a cubic spline interpolation function of the realization of the C code. If interpolation points need to change, the procedures will change.)

说明：  最优化课程中的最速下降法matlab程序，利用了wolfe搜索和armijo线搜索(Matlab program of steepest descent method in optimization course, using Wolfe search and Armijo line search)

湍流模型re计算流体力学软件udf 可以用于修改UDF文件(turbulence model FLUENT)

用matlab编写newmark-B法解结构振动微分方程的程序(Prepared using matlab newmark-B method for solving differential equations of structural vibration program)

大部分机械都是以转子形式运转，这本转子动力学是研究旋转机械动力学的基础(Most of the machinery are operating a rotor and the rotor dynamics is the study of the dynamics of rotating machinery foundation)

三次样条插值函数源代码：对输入的数据采用三次样条插值处理,集成了样条,并返回积分值。(Cubic spline interpolation function source code: the input data using cubic spline interpolation processing, integrated spline, and returns integral values.)

模拟Chaboche非线性随动硬化各向异性塑性的例子 -HILL和CHAB的实例(Chaboche simulation examples of anisotropic nonlinear kinematic hardening plastic -HILL and examples of CHAB)

用来画多输入多输出系统的格式带，输入是矩阵形式(draw gershgorin)

PETSc (Portable, Extensible Toolkit for Scientific Computation) 是美国能源部ODE2000 支持开发的20 多个ACTS 工具箱之一，由Argonne 国家实验室开发的可移植可扩展科学计算工具箱，主要用于在分布式存储环境高效求解偏微分方程组及相关问题。(PETSc (Portable, Extensible Toolkit for Scientific Computation) is ODE2000 U.S. Department of Energy to support the development of one of more than 20 ACTS Toolkit, developed by the Argonne National Laboratory' s Portable, Extensible Toolkit scientific computing, mainly used in the distributed memory efficient environment for solving partial differential equations and related issues.)
