A repository of matrix test data for use in comparative studies of algorithms. The matrices have been taken from problems in linear systems, least squares, and eigenvalue calculations in a wide variety of scientific and engineering disciplines. Includes search for matrices by size, mathematical properties, and keywords.

Symmetric Presentations Well, my research is in group theory which is a part of algebra. In particular, I study symmetric presentations. If you don't know what a group is then click here for a definition. If the reader seeks a representation of a group, then he should refer to the ATLAS of group representations which is maintained by R.A.Wilson and R.A.Parker. We shall give some presentations of ...
