2018-04-23 08:54:01 +0200 | commented answer | Basic work on tensor components Thank you very much! I think it would make sense to add this to the lib (as well as a method doing this in place instead of a root namespace function returning a new object). I use SageManifolds only when computations are complicated, and then I always need simplify and his friends expand and factor. |

2018-04-21 01:04:05 +0200 | asked a question | Basic work on tensor components My SageManifolds notebooks typically start with a bunch of home made function designed to access components of tensors. But they are based on a common hacky function relying on very shallow understanding of the internals of SageManifolds. Am I missing some builtin equivalent? What is the proper way of doing this? ``` |
