Instead of multiple classes for + indexed things and their indices there is now only one "indexed" class + and two types of indices: "idx" for simple indices and "varidx" for + indices with variance. There are predefined delta, epsilon and metric + tensors, and a function simplify_indexed() that performs canonicalization + and dummy index summations. +* Added an option "expand_indexed" to expand() to perform expansion of + indexed objects like (a+b).i -> a.i + b.i +* Renamed get_indices() to get_free_indices(), which no longer returns + dummy indices and checks the consistency of indices in sums. +* subs() works on matrices. + 0.7.3 (28 February 2001) * Several bugfixes and minor performance tunings. * Added a section to the tutorial about adding new algebraic classes to GiNaC. -- 2.44.0
