The problem of joint approximate diagonalization of symmetric real matrices is addressed. It is reduced to an optimization problem with the restriction that the matrix of the similarity transformation ...

Abstract: This communication addresses a new problem which is the Non-Unitary Joint Zero-Block Diagonalization of a given set of complex matrices. This problem can occur in fields of applications such ...

Qiskit addons are a collection of modular tools for building utility-scale workloads powered by Qiskit. This package contains the Qiskit addon for sample-based quantum diagonalization (SQD) -- a ...

The diagonalization of matrices may be the top priority in the application of modern physics. In this paper, we numerically demonstrate that, for real symmetric random matrices with non-positive ...

Abstract: A multichannel extension of nonnegative matrix factorization (NMF) for audio/music data, called multichannel NMF (MNMF), has been proposed by Sawada et al ["Multichannel extensions of ...
