On the trace and eigenvalues of the structure matrix of a graph;

The thermodynamic system structure matrix plays an important role in the analysis for the performance of thermodynamic system in power plant.

In this paper,by an integrated analysis of existing modeling methods of the design process for products,a novel approach to information modeling is proposed based on the expanded directed graph and the fuzzy design structure matrix,and the information dependence of activities is quantitatively described.

A Study of Matrix Structure in University Libraries;

And then the authors raise the basic thinking and the frame of the formation for the course system of the matrix structure in higher normal education of china, which are four horizontal model blocks and two vertical series.

Then, the relationship between the evaluation indexes is researched, and four different kinds of the structure of the evaluation indexes for complex systems, indexes set, tree structure, clump structure and matrix structure, are presented.

Concrete examples are given to show the application of MATLAB to the structural matrix and the advantages of this software in structural calculation.

Boiler is included in structural matrix as an energy level.

In the end,the mapping from connection matrix to structural matrix is built through the algorithm of depth first search,which makes automated modeling successful.

A displacement rank approach to PLU decomposition for a structured matrix;

The main problem considered in this paper is how to find efficiently a nonzero element in the kernel of a given structured matrix by the displacement approach.

Canonical forms for 2 kinds of doubly structured matrices are presented in this paper.

Thus,it is not surprising that in recent years the design of fast algorithms for structured matrices has become an increasingly important activity in a diverse variety of branches of the exact sciences.
