Backlog from 1.0.n: -* Fixed LaTeX output of indexed and matrix objects. +* Powers of indexed objects are now parenthesized correctly in LaTeX output. +* Input parser handles indices (they have to be specified in the same list + as the symbols). +* Added some limited support for subspaces in the idx and tensor classes. +* Fixed a bug in canonicalize() (antisymmetric canonicalization of an already + sorted list containing two or more equal objects failed to return 0). +* simplify_indexed() now raises/lowers dummy indices to canonicalize the index + variance. This allows some simplifications that weren't possible before, + like eps~a.b~c~d*X.a*X~b -> 0 and X.a~a-X~a.a -> 0. +* Implemented relational::subs(). +* Fixed bug in simplify_ncmul() for clifford objects. +* Fixed LaTeX output of indexed and matrix objects and powers thereof. * Fixed matrix::pow(n) for n==0. * "(x+1).subs(x==x-1)" now returns the correct result "x" instead of "x-1". * (l)degree(s), coeff(s, n) and collect(s) were extended to accept expressions
