We in this paper study the reflexive solution of a Sylvester quaternion k-conjugate matrix equation. We first give an iterative algorithm for the solution of the problem. Then we prove that the ...

This software package includes the subspace-conjugate gradient method for linear matrix equations developed and analysed in the manuscript. A subspace-conjugate gradient method for linear matrix ...

Abstract: When only a limited number of snapshots is available for estimating the spatial correlation matrix, a low-rank solution of the MVDR equations, obtained via a small number of iterations of ...
