Decompose a complex symmetric matrix to retain positive definitness
Thanks for that. I haven't quite absorbed your answer fully but it's definitely pointed me in the right direction. In the case of complex matrices, should I consider congruence to be $A -> S^T A S$ (which I have) or $A -> S^H A S$ (valid for Hermitian matrices)?
