算法交易，统计套利，配对交易python代码实现(Algorithm trading, statistical arbitrage, pair trading, Python implementation)

说明：  适用于PCSC型读卡器与CPU卡进行交互的小程序(Small program for interaction between PCSC card reader and CPU card)

本人自编的另一个有限元软件，用来解决电磁声静电场问题。本是一个作业。经了不少心思。可以在程序内建模，加载荷，并求解，彩图显示结果。并输出模型文件，和结果文件。输出的结果文件可以再读入程序进行下一次的分析。(I directed another finite element software, used to solve electromagnetic acoustic electrostatic field problems. This is an operation. After a lot of efforts. The procedure modeling, load, and solving color pictures show results. Model and output documents, and the outcome document. The output of the document can be read into the process for the next analysis.)
