| 2015-01-06 22:45:41 +0200 | asked a question | Error plotting root systems in Sage I am trying to use the Sage package for root systems, but it keeps returning an error. Here is what I am trying to do in the Notebook of Sage 5.7: I enter exactly the following lines from the tutorial for visualizing root systems sage: L = RootSystem(["A",2]).ambient_space() sage: L.plot() The output I get is a traceback ending in 'unsupported operand parent(s) for '*': Full matrix Space of 2 by 2 dense matrices over real field with 53 bits of precision and vector space of dimension 3 over rational field' I do not understand what I am doing wrong and what this message means. I am a newcomer to sage and all I want is to print a root system with some weights added for illustration purposes. I would appreciate any pointers. |
