Butterworh滤波器程序

simple 算法，有详细步骤，几乎步都自带注解，很好理解。(simple algorithm detailed steps to bring their own annotations)

说明：  复合材料疲劳寿命预测umat程序，用Fortran语言编写，在ABAQUS中应用(Composite fatigue life prediction UMAT program, written in Fortran language, and applied in ABAQUS)

逐步回归分析，挺好用，你值得拥有，别人给的资料(Stepwise regression analysis)

VUAMT-Hashin三维参数退化渐进损伤程序(VUAMT-hashin 3D for FRP analysis)

PSCAD interface with C

用于矩阵的一种cholesky分解方法，第一次上传请多关照(cholesky method for matrix decomposition)

基于pscad的mmc逆变模型，仅含有逆变部分，借鉴别人的，仅供参考。(Based on PSCAD MMC inverter model, only contains the inverter part, learn from others, for reference only.)

AIEM，改进的积分方程模型。版本为台湾陈焜山教授修改后的最后版本，主要用于裸露地表微波辐射传输模拟(AIEM, Advanced Integral Equation Models. Taiwan version of the final version of Professor Chen Kun Shan modified, mainly for the bare surface of microwave radiative transfer simulation)

复合材料疲劳寿命预测umat程序，用Fortran语言编写，在ABAQUS中应用(Composite fatigue life prediction UMAT program, written in Fortran language, and applied in ABAQUS)

pscad做的整流器控制模型，运行效果良好(Rectifier control model of PSCAD, good results)
