摘要
In this paper, our discussion is based on Zeilberg＇s basic idea and use an elimination in the non-commutative Weyl algebra to get the differential operator. Thereby we can obtain the algorithm of proving identities of the form ∫∞ -∞F（x, y）dy = a（x）.
熵是一个分布的重要信息特征,通过对矩阵变量积分的一些技巧,利用矩阵Γ分布的特征,本文获得了矩阵F分布和矩阵Beta分布的熵.
