Locally Optimal Block Preconditioned Conjugate Gradient (LOBPCG) is a matrix-free method for finding the largest (or smallest) eigenvalues and the corresponding eigenvectors of a symmetric generalized eigenvalue problem
for a given pair of complex Hermitian or real symmetric matrices, where
the matrix is also assumed positive-definite.
