python 程序

说明：  《有限元方法编程（第三版）》随书源码。 采用 Fortran 90 编制，近 400 个计算子程序。在 64 位机器上编译通过，并运行正确。( Finite Element Method Programming (Third Edition) With the book source. The preparation of the use of Fortran 90, nearly 400 calculation subroutine. 64 machines in the compiler is passed, and run correctly.)

用于模拟混凝土单元的弹塑性模型，并有损伤变量，在ABAQUS中umat中输入弹性模量，泊松比与屈服应力即可。(The elastic-plastic model for the simulation of concrete unit, and the damage variable in the ABAQUS umat enter the elastic modulus, Poisson' s ratio and yield stress can be.)

说明：  相变UDF，包括质量传递和热量传递，能够进行气液相变的模拟(Phase transition UDF, including mass transfer and heat transfer, gas-liquid phase transition can be simulated)

介绍线性算子的基本概念的文章,这是书里面的一个章节(Foundation of linear operator theory)

说明：  这是一个处理脑电信号的程序，可以辅助脑电信号处理程序的使用(This is a process of eeg signal, can assist the use of eeg signal processing program)

Umat Abaqus for plasticity

分数阶傅立叶变换程序总结，共有6个程序。(Fractional Fourier Transform program summary, a total of six procedures.)

this is a source code written in the matlab format for the teaching learning optimization algorithm.

说明：  九维的卡尔曼滤波跟踪算法，包括xyz三方向和各方向的位置，速度，加速度。(Nine-dimensional Kalman filter tracking algorithm, including the three xyz direction and the location of the direction, velocity, acceleration.)

利用AR模型进行时间序列预测的程序源代码，使用最小二乘估计法进行参数估计。拟合效果非常好。(use AR model for time series prediction of the source code, the use of least squares estimation method to estimate parameters. Fitting very good results.)
