1) non-zero element
非零元素
1.
A procedure to assemble only non-zero element of a global stiffness matrix of finite element analysis in a one-dimensional array was proposed,which utilizes cell element index storage scheme.
基于细胞元索引存贮方案,提出一种仅组集有限元刚度矩阵中非零元素的方法,该方法最突出的特点是计算所需内存空间与有限元网格节点和单元的编号模式无关,适于进行自适应网格细化有限元分析。
2) nonzero elements chain
非零元素链
1.
In this paper,some sufficient conditions for a matrix to be a generalized strictly diagonally dominant matrix are given by nonzero elements chain theory and other methods,which generalize criteria of generalized strictly diagonally dominant matrix.
利用非零元素链理论以及方法,给出了判定广义严格对角占优矩阵的几个充分条件,拓广了广义严格对角占优矩阵的判定方法,并给出其在神经网络系统中的应用,结果表明该法不仅有效而且简单实用。
2.
On this base,this concept of local(α,β,γ)-doubly diagonally dominant matrix with a nonzero elements chain is introduced and a new criterion for nonsingular H-matrix is presented.
在此基础上,定义了具非零元素链的局部(α,β,γ)-双对角占优矩阵概念,并且获得了非奇异H-矩阵新的判别方法。
3.
