摘要： 本文介绍了当矩阵数据大于主存贮器容量时,用微机或小型计算机转置大矩阵的三种算法.矩阵数据可贮存在磁盘或磁带外存设备上.试验结果证明,算法具有显著的快速性优点.

Abstract: The purpose of this paper is to present three algorithms for transposing large matrices of whnich data are larger than main memory available. The data can be stored on external storage device, such as disk or magnetic tape. The transposing operations using 128*256 matrices have been carried out on PDP11/24 minicomputer. Experimental results demonstrated that tie algorithms could realize a speed advantage.
