Re: [sympy] Multiple types of Coordinate Systems for Vectors

Hi Brombo, Can you suggest some API specification for the new coordinate system? Thanks On Thursday, January 12, 2017 at 12:49:02 AM UTC+5:30, Arihant Parsoya wrote: > > The link to the PR is https://github.com/sympy/sympy/pull/12020 > > On Thursday, January 12, 2017 at 12:37:35 AM UTC+5:30, Ar

Re: [sympy] Multiple types of Coordinate Systems for Vectors

Hi, I have submitted a PR which implementes classes *CoordinateSystem* (Super class for remaining coordinate systems), *CartesianCoordinateSystem* and *SphericalCoordinateSystem* using Metric and Lamè coeffecients here . Can you

My notes base on "Geometric Algebra for Physicists" are at - https://github.com/brombo/galgebra Look at bookGA.pdf in the doc directory. On Sun, Dec 11, 2016 at 8:53 AM, Arihant Parsoya wrote: > Hi, > > I am trying to get myself acquainted with geometric algebra by following > the book `Geomet

Re: [sympy] Multiple types of Coordinate Systems for Vectors

Hi, I am trying to get myself acquainted with geometric algebra by following the book `Geometric Algebra for Physicists` (by Chris Doran). It would be very helpful if you can suggest some other readings which can be helpful in implementing the class `coordinate_system`. Thanks On Saturday, O

Re: [sympy] Multiple types of Coordinate Systems for Vectors

If you use the methods in galgebra.pdf remember (this is documented) that for all but rectangular coordinates the basis vectors derived from the metric are not normalized. Especially go over section 2.3.2 is galgebra.pdf. On Sat, Oct 1, 2016 at 1:10 AM, Arihant Parsoya wrote: > Hi Brombo, > > I

Re: [sympy] Multiple types of Coordinate Systems for Vectors

Hi Brombo, I went through galgebra.pdf file and I believe this approach would be good. Initially I want to implement Cartesian and Spherical coordinate systems and get them right before implementing other systems. On Friday, September 30, 2016 at 10:19:39 PM UTC+5:30, brombo wrote: > > In 3 dim

Re: [sympy] Multiple types of Coordinate Systems for Vectors

In 3 dimensions there are 13 separable (orthogonal) coordinate systems. See link - https://en.wikipedia.org/wiki/Orthogonal_coordinates How many do you want to implement? I would have a coordinate_system class and use it to instantiate a particular coordinate system then when you instantiate a v

Hi All, I wanted to work on the idea of Multiple Coordinate Systems. Previously I submitted my PR for the same here . The old PRs related to this idea uses Lame` coeffecients whereas the GSOC ideas page
