The Lanczos approximation, often referred to as the Lanczos algorithm, is a numerical method primarily used for solving problems related to large sparse matrices. It is particularly effective for computing eigenvalues and eigenvectors of such matrices. The algorithm is named after Cornelius Lanczos, who developed it in the 1950s.
