NEPv Approach for Optimization on Stiefel Manifold with the $(2,1)$-norm Regularization

A unifying NEPv framework is established to efficiently deal with optimization on the Stiefel manifold with the $(2,1)$-norm regularization and numerical experiments are presented to illustrate the use of the NEPv approach and to gain insights as to what a proper regularizing parameter should have in real-world applica...
