PCA - Principal Component Analysis in FPC

 :) Hello :)
I did some googling and could not find: does anyone have a source code example about how to calculate PCA with FPC?

I have attached some code that does it based on a SVD approach documented in this article: https://arxiv.org/pdf/1404.1100.pdf

The SVD routine is a port of the Numerical recipes one nice-ified, but it will be under the normal numerical recipes license of course
