2013-01-22 10:40:02 -0500 | marked best answer | How to do symbolic computation with quaternions You should define |

2013-01-21 20:37:05 -0500 | asked a question | How to do symbolic computation with quaternions I need to do symbolic computations with quaternions. Ideally I'd like to enter something like But it doesn't work : TypeError: unsupported operand parent(s) for '*': 'Symbolic Ring' and 'Quaternion Algebra (-1, -1) with base ring Rational Field' Looks like SAGE doesn't know how to multiply a variable and a quaternion. Or should I specify the types of the variables ? How ? Thanks for your help. |
