I think that Raoul's post takes care of the requirement of the list. Also, I will still take some time to write the proposal on the wiki. First, I want to be really clear on exactly what to implement and, more importantly, how to implement. And sure, we can implement all things on a Cn over C vector space. Raoul also mentioned the 7 dimensional cross product. > Maybe one could even fill up R4,R5,R6 to R7? But that > I never tried. Neither have I. So, let me. Though a first glance at Cayley's sample multiplication table (in the wikipedia page mentioned) reveals that the 7 dimensional cross product may generalize all the way down to 1 dimension. This I say because the cross product of ei, i=1, 2, 3, is same as for cross product in R3. So, this looks hopeful. Anyway, in the meantime, I have been jotting down ideas as they come to me on a whiteboard and copying them down in a notebook. Right now, I am trying to deal with coordinate systems and how best to implement them in a class. Some ideas include user defined bases, conversion matrices between different coordinate systems, conversion between different bases etc. After I have a basic visualization of the structure of the coordinate system class, I'll post my ideas here. Then, next thing I will focus on is the concept of Reference Frames and a world based coordinate origin. Until then, please feel free to post any ideas/suggestions/opinions, however small, over here. Thanks for the valuable inputs everyone. Much appreciated. -- You received this message because you are subscribed to the Google Groups "sympy" group.
