I want to calculate the eigenvector corresponding to the $0$ eigenvalue of a large, sparse singular matrix. However, if I try eigs(A,1,'smallestabs'), MATLAB has an issue due to it being singular. For smaller matrices, eig works fine, but I need something that will work with larger matrices. Is there any way I can get eigs to work with this?
I'm open to other languages/ writing my own algorithm if need be as well.
