LOBPCG occasionally returns NaN as least eigvec/eigval #20

Closed alanpapalia closed 7 months ago

alanpapalia commented 7 months ago

In attempting to compute a 2nd order descent direction via LOBPCG we are occasionally obtaining a NaN value as the least eigenvalue and a vector of NaNs as the corresponding eigenvector. This is currently what is causing a test to fail in https://github.com/MarineRoboticsGroup/cora-plus-plus/pull/19/commits/88648de590e30364e34ab77ca81d80abb3f3dfde
