LOBPCG stands for Locally Optimal Block Preconditioned Conjugate Gradient. It is an iterative method used for the computation of a few eigenvalues and associated eigenvectors of large, sparse, symmetric (or Hermitian) matrices. The method is particularly well-suited for problems where one is interested in the smallest or largest eigenvalues of a matrix, which is common in various fields such as quantum mechanics, structural engineering, and principal component analysis.
