An implementation of Tarj an's algorithm for symmetrically permuting a given matrix to block
tmangular form is described. The discussion includes a flowchart of the algorithm, a
complexity analysis, and a comparison with the earlier widely used algorithm of Sargent and
Westerberg. T~ ming results are presented from several experiments using the code
developed by the authors.
