This paper introduced a method for AutoCAD Modeling, in which the method of drawing AutoCAD surface from matrix data by Active X Automation technology is discussed.

Assessment of influence in condition indexes of data matrix;

DOA estimation of coherent signals based on data matrix

The receiver focus of backwards continuation of upgoing wavefield at that depth point can be fulfilled by using data matrix to carry out post-time-shift weighted stack, The source focus of backwards continuation of downgoing wavefield at that depth point can be fulfi.

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.
