摘要:

本文的主要目标是开发一个基于客户端/服务器的模型,用于使用分区方法计算加权Moore-Penrose逆以及存储生成的结果。该Web应用在PHP/MySQL环境中开发。源代码是开放的,可通过Web浏览器免费测试。研究了不同矩阵表示和存储系统对计算时间的影响。将搜索先前存储的伪逆的CPU时间与重新计算相同逆的CPU时间进行了比较。

英文摘要:

The main aim of this paper is to develop a client/server-based model for computing the weighted Moore-Penrose inverse using the partitioning method as well as for storage of generated results. The web application is developed in the PHP/MySQL environment. The source code is open and free for testing by using a web browser. Influence of different matrix representations and storage systems on the computational time is investigated. The CPU time for searching the previously stored pseudo-inverses is compared with the CPU time spent for new computation of the same inverses.
