Conjugate Gradient Algorithm for Optimization under Unitary Matrix Constraint
In this paper we introduce a Riemannian algorithm for minimizing (or maximizing) a real-valued function J of complex-valued matrix argument W under the constraint that W is an n×n unitary matrix. This type of constrained optimization problem arises in many array and multi-channel signal processing a...
