Positive Semidefinite Hankel Structured Low Rank Approximation using Vandermonde Decomposition
2019 Fifth Indian Control Conference (ICC), 2019In this paper, we propose a decomposition based method for solving the positive semidefinite Hankel structured low rank approximation (PHSLRA) of a given matrix. This problem is formulated as an unconstrained optimization problem using the Vandermonde decomposition of the positive semidefinite Hankel matrix.
