Hankel tensors: Associated Hankel matrices and Vandermonde decomposition
Hankel tensors arise from applications such as signal processing.In this paper, we make an initial study on Hankel tensors.For each Hankel tensor, we associate a Hankel matrix and a higher order two-dimensional symmetric tensor, which we call the associated plane tensor.If the associated Hankel matrix is positive semi-definite, we call …
