Is everything what you have mentioned implemented ?? I was thinking on these lines :
Given a system we have a matrix to compute the contravaraint co ordinates wrt to the original basis (The given basis). In covariant coordinates the basis itself have a different representation but this would also be computed wrt to the original basis.And we can have these under various co ordinate systems Co ordinate Spherical Helicity Cylindrical Polar (conversions between each on of these) The next would be given any set of basis in any co ordinate systems there would a test whether or not these would form the basis and give out the co ordinates And this can even be extended to polynomial basis where the basis are polynomial and we can have field implementation for the co ordinates in the polynomial space. I guess this sound feasible enough and I would like to know if there has been an implementation regarding any of these. Thanks.
