### Subset of eigenvalues and eigenvectorsMATLAB eigs

The eigenvalues are clustered near zero. The smallestreal computation struggles to converge using A since the gap between the eigenvalues is so small. Conversely the smallestabs option uses the inverse of A and therefore the inverse of the eigenvalues of A which have a much larger gap and are therefore easier to compute.This improved performance comes at the cost of factorizing A which
