canform

Maxima Function

Calling Sequence

canform (expr)

Description

Simplifies expr by renaming dummy indices and reordering all indices as dictated by symmetry conditions imposed on them. If allsym is true then all indices are assumed symmetric, otherwise symmetry information provided by decsym declarations will be used. The dummy indices are renamed in the same manner as in the rename function. When canform is applied to a large expression the calculation may take a considerable amount of time. This time can be shortened by calling rename on the expression first. Also see the example under . Note: canform may not be able to reduce an expression completely to its simplest form although it will always return a mathematically correct result.
