Rearranging Expressions by Patterns

Volume 4, Issue 3
Summer 1994
Jason F. Harris, University of Canterbury, New Zealand

The package PatternRearrange.m defines two functions, PatternCollect and PatternGather, that perform algebraic simplification by rearranging expressions according to patterns. The functions provide much more control over how expressions are rearranged than built-in functions such as Collect, Factor, and Simplify.
