The Matrix Market Exchange Formats: Initial Design

The Matrix Market (MM) exchange formats provide a simple mechanism to facilitate

the exchange of matrix data. In particularthe objective has been to define a minimal

base ASCII format which can be very easily explained and parsed but can be easily

adapted to applications with a more rigid structureor extended to related data objects.

This format is the primary format used by the Matrix Market visual database of matrix test data available on the World Wide Web.
