MAGUS(R) RELEASES VERSION 3.0 OF NUMERICAL ANALYST(TM)
FOR MICROSOFT(R) FORTRAN OPTIMIZING COMPILER
Mountain View, California, June 18, 1990 -- MAGUS, a leading
supplier of mathematical software for personal computers and
workstations, announced today a new version of its scientific
subroutine library, Numerical Analyst.
Numerical Analyst is an object library of mathematical
subroutines and functions callable from Fortran. The new
version, 3.0, is currently available for Microsoft Fortran
version 5.0 under the MS-DOS(R) and MS(R) OS/2 operating systems.
Capabilities of Numerical Analyst 3.0 include derivatives
and integrals of discrete data; ordinary differential equations;
eigenvalues and eigenvectors of matrices; singular value
decomposition; mathematical functions; interpolation and curve
fitting; solution of linear equations; solution of nonlinear
equations; numerical integration; basic statistical functions;
fast Fourier transforms; vector and matrix operations;
minimization of functions; nonlinear optimization; and all roots
of polynomials.
"Version 3.0 of Numerical Analyst represents a quantum leap
in functionality over version 2.1," said Dr. Kevin Thompson,
Technical Director and a founder of MAGUS. Version 3.0 includes
entirely new capabilities, such as eigenvalues and eigenvectors
of matrices, as well as improved techniques for capabilities
included in earlier versions of the library.
Several architectural improvements implemented in version
3.0 set it apart from earlier versions of Numerical Analyst and
from other commercially available mathematics libraries. Primary
among these is error analysis. Every subroutine whose results
cannot be guaranteed to machine precision provides an estimate of
their accuracy. Second is error handling. In version 3.0, error
handling can be customized by the user. Error messages may be
suppressed or directed to files. Default response to fatal
errors may be overridden. This feature allows a user program to
select a secondary approach to solving a problem when the first
approach fails.
The Numerical Analyst user documentation was completely
rewritten for version 3.0. "Our Reference Manual sets a new
standard for clarity and ease of use," said Thompson. The manual
describes in detail the mathematical problems to be solved. Each
subroutine description is preceded by a discussion of the
numerical algorithm employed, with emphasis on its capabilities
and limitations. Numerous sample programs, which are useful both
as a learning aid and a starting point for development, are
included on disk as Fortran source files as well as printed in
the relevant section of the manual.
Numerical Analyst for Microsoft Fortran is priced at $450.00
for single-user licenses. Academic and volume discounts are
available. Licensed users of Numerical Analyst versions 2.0 and
2.1 may upgrade to version 3.0 for $100.00.
Version 3.0 of Numerical Analyst for Microsoft Fortran is
currently shipping to customers. Inquiries about the product
should be addressed to MAGUS at P.O. Box 390965, Mountain View,
