A survey of language-oriented systems for numerical linear algebra

The manipulation of matrices and the solution of linear algebraic equations are the most frequently encountered tasks in scientific computing. Because linear functions are best understood, problems in computer science, statistics, engineering, mathematics, and optimisation tend to be formulated as sequences of linear systems.

For the ‘low-level’ user who has to solve problems in liner algebra (i.e., one who has no need to learn FORTRAN, PL/I, or Algol), an approach which is most practical is to provide a programming system for linear algebra that will automatically give a reliable solution to the problem at hand. This paper gives a brief description of a number of such systems, including an example program written for each.

Received October 1972.
