The purpose of this paper is to briefly examine several | |
of the major issues concerning the development of | |
numerical mathematical software and numerical | |
mathematical software libraries. The paper begins with a | |
brief summary of the evolution of general-purpose | |
mathematical software libraries. This is followed by an | |
introductory discussion on software reliability. It is | |
often tacitly assumed that most of the basic numerical | |
mathematics problems have satisfactorily been solved. | |
This is shown not to be the case. Indeed, it is noted | |
that many of the problems encounter not only deep | |
theoretical difficulties, but also numerous software | |
engineering problems. The next major topic is software | |
portability. Here the emphasis is on portability | |
difficulties that arise from design deficiencies in the | |
programming languages. It is noted that FORTRAN permits | |
an arithmetic expression to be altered when it is known | |
that the modification can produce different results. The | |
final issues considered are those involved in forming a | |
library. If the purpose of the library is to serve as | |
broad an audience as possible, then it is recognized that | |
the subroutines in the library should be as simple to use | |
and as comprehensive as is practical. Thus formation of | |
the library can be characterized as a packaging problem, | |
the objective being to package mathematical formulae and | |
theory into comprehensive, simple-to-use subroutines. | |
