By breaking [Formula: see text] into disjoint subsets and its complement, a new -type upper bound for the largest singular value of nonnegative rectangular tensors is given and proved to be better than some existing ones. Numerical examples are given to verify the theoretical results.
通过将[公式:见文本]划分为不相交子集及其补集,给出了非负矩形张量最大奇异值的一种新型上界,并证明其优于一些现有上界。给出了数值例子以验证理论结果。
