complex symmetric matrix, complex symmetric operators and matrices, unitary equivalence, unitary similarity, unitary orbit, tranpose, UECSM
We develop a procedure for determining whether a square complex matrix is unitarily equivalent to a complex symmetric (i.e., self-transpose) matrix. We compare our approach to several existing methods [1, 19, 20] and present a number of examples.
