An -type singular value inclusion set for rectangular tensors is given. Based on the set, new upper and lower bounds for the largest singular value of nonnegative rectangular tensors are obtained and proved to be sharper than some existing results. Numerical examples are given to verify the theoretical results.
给出了矩形张量的一种(A_n)型奇异值包含集。基于该集合,得到了非负矩形张量最大奇异值的新的上下界,并证明这些界比一些现有结果更精确。给出了数值例子来验证理论结果。
