elements of main diagonal 主对角线上的元素
negative elements of main-diagonal 主对角负元
This paper USES a new method to determine the diagonal elements of the matrices.
对于对角线元素,本文使用了一个新的方法予以确定。
It is proved that the stiffness matrix of the finite element solution is a block diagonal matrix and its elements are some symmetric and block circulant submatrices.
证明了有限元求解的刚度矩阵是一个块对角阵,且其子矩阵是某种对称、块循环矩阵。
Since all elements on the primary diagonal are 1s and the dimensions are less than 2006, the graph with A2006 as its adjacency matrix is the transitive closure of the graph represented by a.
由于主对角线上的元素都是1,而且矩阵的阶小于2006,所以为a2006邻接矩阵的图就是由A表示的图的传递闭包。
