Preferably something which is (or could be) parallelized, but not necessary. Any help would be appreciated. David A.

The revised technical report which has same text as the accepted paper can be obtained by anonymous ftp to matisa.cc.rl.ac.uk (130.246.8.22). The gzipped postscript is in file dmrvRAL95049.ps.gz in directory pub/reports. For copyright reasons, this may not be available for long, so download your copies early! The referees were keen that we did not claim that this is a standard, but hopefully this work will help to focus efforts at establishing standard interfaces to the sparse BLAS.

The aim is to link professionals from the diverse fields of * mathematics, * computer science * physics, * chemistry, * environmental sciences, * biosciences and * engineering. The rapid development of computer technology has opened up new perspectives, increased the importance of mathematical models and created an urgent need for efficient algorithms. Reflecting these trends, the journal has set itself the goal of publishing pioneering methods and applications which precipitate the solution of complex problems - or even make such solutions possible at all. Since visualization has become an important scientific tool, especially in the analysis of complex situations, it is treated in close connection with the other areas covered by the journal. These areas include: * mathematical modeling and analysis of model systems * numerical methods and algorithms * development of simulation software * optimization and control * parallel computing * visualization and image analysis * computational physics and chemistry * structural mechanics * fluid dynamics * environmental sciences * computation in biosciences and medicine * modeling and computation in engineering As well as publishing this exciting material in print form, Computing and Visualization in Science will also make the documents available to subscribers electronically via a server.
