Numerical range for weighted Moore-Penrose inverse of tensor [PDF]

open access: greenThe Electronic Journal of Linear Algebra, 2022
This article first introduces the notion of weighted singular value decomposition (WSVD) of a tensor via the Einstein product. The WSVD is then used to compute the weighted Moore-Penrose inverse of an arbitrary-order tensor. We then define the notions of
