Implementation on multi-directional computing of real number model represented by unit group

This article is to achieve the multi-directional computing of real number models,based on multi-directional computation of unit group models.The research on multi-direction computation is based on and supported by the group theory and the graph theory.An abstract algebra group composed of one element is the highest abstraction of the mathematical models researched in this paper.The aprovement of multi-directional computation of the group is finished in this paper.Mathematical models in real number domain applied multi-directional computing of one element group and those are widely used in the scientific computing and the engineering computing.A software system,named Jiuzhang,is established based on these researches.Jiuzhang deals with mathematical model composed of elementary algebra operations and performing multi-directional computation on the mathematical model.The key characteristic of Jiuzhang is that it is able to perform multi-directional computation on the mathematical model.Draw out the mathematical model from the application program and performed by Jiuzhang with the performance of multi-directional usage of the mathematical model.
