We propose a new iterative algorithm for generating a subset of eigenvalues and eigenvectors of large matrices which generalizes the method of optimal relaxations. We also give convergence criteria for the iterative process, and investigate its efficiency by evaluating computer storage and time requirements and by a few numerical tests.
