【摘要】 在多谱变换隐式重启动 Arnoldi( IRA)算法结构设计中 ,采用泛函表述实现了谱变换和 IRA算法解耦 ,产生了相对独立的 IRA对象和多种谱变换对象。然后应用设计模式概念 ,根据多谱变换下 IRA算法凝固点—热点结构和设计模式模板—挂钩结构的对应关系 ,提出基于设计模式结构的多谱变换 IRA算法组合结构。该算法结构的实际应用充分证明了其在软件系统可伸展性、可重用性和计算效率方面的优势。更多还原

【Abstract】 In the structure design of the multi-spectrum transformation implicit restarted Arnoldi (IRA) algorithm. this paperfirstly decouples the main part of the IRA algorithm from multi--spectrum transformations by adopting the functionalexpressions. and then produces the IRA and spectrum transformation objects which are independent of each other.Furthermore. by applying the design pattern approach. and according to the relationship between the stable point-hot POintstructure and the template--hook structure of design patterns, a novel multi-spectrum transformation IRA algorithm structureis finally given based on design patterns. The real applications of this algorithm structure show its advantages enough inexpandability. reusability and calculation efficiency of software system.This is the National Science and Technology Key Project (No. 97-312-l-11-ie).更多还原
