Do you have any code about PCA for classificatin in MATLAB or Python?

06 June 2015 1 863 Report

Hi,

I need PCA (principle component analysis) code for classification. I would like to use it for fault diagnosis. Thus, the problem is multi-class not just binary-class. I would be grateful if you may introduce a source code.
