tangent modulus martrix

Given the matrix normal model where ∑>0 and V>0 are known, it is showed that S1YS2 is admissible for S1 S2 in the class of all estimators under each of six definitions for admissibility.

對于矩陣正態模型Ｙｎｘｍ～Ｎ其中０和Ｖ≥０已知，本文征明了，在６種不同的可容許性定義下，Ｓ１ＹＳ２在一切估計類中是Ｓ１Ｓ２的可容許估計。

It has proved the theory that fuzzy matrix A is a λ-cut invertible fuzzy matrix if and only if A is a orthogonal fuzzy matrix, and obtain a method of all λ-cut inverse fuzzy matrix to solute λ-cut invertible fuzzy matrix.

提出了λ截可逆模糊矩陣的概念，討論了λ截可逆模糊矩陣的性質，證明了模糊矩陣A是λ截可逆模糊矩陣的充分必要條件為A是正交模糊矩陣，給出了求λ截可逆模糊矩陣A的全部λ截逆模糊矩陣的方法。
