Summary

Written/ hardcopy computer program titled 'Solution of system of linear equations: AX=B, by inverting matrix A, then multiplying the inverse by vector B', DECUS Program library number 8-74, April 1967. Author: Professor A.E.Sapega. Trinity College, Connecticut. Published by the Digital Equipment Computer Users Society, Massachusetts.

Abstract: This program solves the set of linear algebraic equations AX=B by inverting matrix A using a Gauss-Jordan method. Fortran source code listing supplied.

The Digital Equipment Computer Users Society (DECUS) was set up by early users of the PDP-1 computer, which was manufactured by Digital Electronic Corporation (DEC), in Massachsetts, United States of America. The creation of DECUS was driven by the need to share information and computer programs for the PDP-1. One of the key reasons was that early users had to write their own software; DEC initially sold only hardware. Set up in 1961, DECUS grew to be one of the largest international societies of computer users in the world.
