eigsh

##I have a graph laplacian, for which I need to find out the largest 'k' eigen values and #eigen vectors. I am using something like this :-
# L= laplacian matrix.
##########################################################################################
eigVal,eigVectors = eigsh(L, nk,  which='LA')

##This is giving me approximately correct results, but something's going wrong and I am #getting eig values slightly greater than 1 (say 1.05). In my case the eigen values are upper #bounded by 1. when using MATLAB and other platforms I am getting desired results.

## What am I doing wrong here??
