这是关于PCA主成分分析降维，文件夹里有.mat格式的数据文件，里面数据可供测试PCA降维使用。(This is about PCA principal component analysis dimension reduction, folder. Mat data file format, data available for test use PCA dimensionality reduction.)

说明：  MATLAB数学实验之数值微分与数值积分，里面有课件以及作业，含程序以及分析过程(MATLAB Mathematical experiments and numerical differential numerical integration, and they courseware and operations, including procedures and analysis process)

ANC算法的前馈实现，它可以实现噪声的消除，有相关的做这个的人也可以跟我交流，我遇到问题了。。13548074570(the anc used feedforward)
