This issue proposes the addition of functionality to SageMath for computing the Poincaré normal form of Riemann matrices. This capability is currently absent in SageMath and would significantly ...
ABSTRACT: MINRES-CN is an iterative method for solving systems of linear equations with conjugate-normal coefficient matrices whose conspectra are located on algebraic curves of a low degree. This ...
ABSTRACT: It is known that if A∈Mn is normal (AA*=A*A) , then AA￣=A￣A if and only if AAT=ATA. This leads to the question: do both AA￣=A￣A and AAT=ATAimply that Ais normal? We give an example to show ...
Abstract: It is known from the transformation theory of matrices that normal matrices can be brought to thed iagonal form by means of a similarity transformation. On the other hand, any diagonal ...

Abstract: Normal-form fixed-point state-space realization of IIR (infinite-impulse response) filters are known to be free from both overflow oscillations and roundoff limit cycles, provided magnitude ...
