This paper presents another method based on the screw theory and kinematics output matrix,which can conveniently calculate the degree of freedom of terminal link about serial robot,and meanwhile lay good foundation for researching the parallel robot.

A Method to Find the Transitive Closure of A Relation by Common Matrix Operation;

The Realize of Matrix Operation Based on FPGA;

This paper studies matrix calculation about input & output analysis method, and uses the method to forecast input & output cost of enterprises with the help of Excel software, so as to make the method applied more broadly.

The author discusses the advantages of using Matlab to do structural dynamic analysis in matrix calculation and drawing .

This method gives vector solution of mesh current or any arbitrary output solution vector by matrix calculation.

The set of linear equations with an irrigular coefficient matrix is solved by using the function about matrix operations in Microsoft Excel,the programming function in Microsoft Excel can also be used to solve the linear equations and find the rank of a matrix.

Weighted Fuzzy Petri Net is combined with matrix operations,and a reasoning algorithm is proposed to achieve the reasoning of knowledge.

In this paper,two methods in calculations of circuit equations are introduced particularly,one is matrix operations,and the other is programming function.
