2011-09-21 04:56:36 +0200 | commented answer | simplify_full() and symbolic vectors That indeed works. Awesome, thanks a lot! Judging from what you're saying, this could be worth a feature request. I'll dig around for where I can file one. |

2011-09-21 04:55:38 +0200 | marked best answer | simplify_full() and symbolic vectors Here is a workaround: It seems that the Vector_symbolic_dense class is quite new (judging by the content of (I think addition and scalar multiplication are desirable for a class implementing vectors). For some reason |

2011-09-20 17:37:30 +0200 | asked a question | simplify_full() and symbolic vectors First, the question: Suppose I've constructed some vectors with symbolic entries, call them P0 and P1. Calling simplify_full on them will -- apparently by changes introduced in the latest version (#11335 and #11381)! -- do an elementwise simplification. Great! Suppose I construct a new symbolic vector by, say, interpolating between P0 and P1: Now produces whereas and work just fine. Somehow the symbolic vector-ness is forgotten in the construction of Pt. Am I doing something wrong? Then, the disclaimer: A friend pointed me to Sage today, and this is the first thing I'm trying to do with it -- I do have background in some other symbolic tools, but this may just be a Stupid User Error despite giving this my best shot and looking at documentation. Anyway, I'm very impressed with what I'm seeing when I look at Sage. (For completeness' sake, here's a full example: Now both return (0,0) as they should. But returns the above error.) |
