2013-09-17 11:11:42 +0200 | commented question | Generic matrix In maple, there is a built-in data-type for this purpose, (that is, for being an element of a symbolic matrix,) called "indexed", and it is a rather low-level thing. I'm new in python/sage, so I don't know whether it's a trouble to implement this. But that would be very very useful. Until that point, tcfisher's answer in http://ask.sagemath.org/question/152/symbolic-linear-algebra offers a workaround. |
