Symmetries are described by a tree of "symmetry" objects that is constructed with the sy_none(), sy_symm(), sy_anti() and sy_cycl() functions. The symmetry of a function with respect to its arguments can also be defined (this is currently only used for the Beta function). -* color_trace() and dirac_trace() can be applied to a more general class - of expressions, e.g. using it on a relation will take the trace on both - sides etc. * Generalized map() to take a function object instead of a function pointer. This allows passing an arbitrary number of additional state to the function being called. +* color_trace(), dirac_trace(), diff(), expand(), evalf() and normal() work + better with container classes, e.g. using color_trace() on a relation will + take the trace on both sides, using diff() on a matrix differentiates every + element etc. +* diff() works properly with non-commutative products and indexed objects. * Supplement some (now deprecated) macros by inlined template functions: - is_of_type(foo, type) -> is_a(foo) - is_ex_of_type(foo, type) -> is_a(foo) - is_exaclty_of_type(foo, type) -> is_exaclty_a(foo) - is_ex_exaclty_of_type(foo, type) -> is_exaclty_a(foo) - ex_to_foobar(baz) -> ex_to(baz) +* rem(c, p[x], x) erroneously returned p[x] instead of c. 0.9.0 (7 June 2001) * In the output and in ginsh, lists are now delimited by { } braces, and
