eigenvalues and eigenvectors scipy
I was wondering which method does [scipy.sparse.linalg.eigs][1] actually implement to calculate the first k eigenvalues and eigenvectors.
I found this http://en.wikipedia.org/wiki/List_of_numerical_analysis_topics#Eigenvalue_algorithms but which one is actually implemented.

It is always helpful to check the documentary first. If this does not help, you could review the source code yourself to find out which method is used.

Quick look in the scipy documentary yields:
This function is a wrapper to the ARPACK 1 SNEUPD, DNEUPD, CNEUPD, ZNEUPD, functions which use the Implicitly Restarted Arnoldi Method to find the eigenvalues and eigenvectors
