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。
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.
海森矩阵被应用于牛顿法解决的大规模优化问题。混合偏导数和海森矩阵的对称性海森矩阵的混合偏导数是海森矩阵非主对角线上的元素。
Hessian matrices are used in large-scale optimization problems within Newton-type methods because they are the coefficient of the quadratic term of a local Taylor expansion of a function.
与露台建筑相对来看，这种元素被减弱了，因此，空间上强调的是前面所提到的主对角线上的视觉效果（东南偏南）。
This element is receded, in relation to the volume of the terrace, so the spatial emphasis is on the main diagonal visuals previously mentioned (south-southeast).
