| 2016-12-08 07:27:59 +0200 | asked a question | building matrices/vectors recursively Suppose that a is a vector, s is a scalar and I am trying to build (say) b=[a; a*s] (a vector twice as long as a). How do I accomplish this with sage? the default behavior will be for b to be a vector with 2 entries, each of which is a vector. But what I wanted is a vector that is effectively twice as long as a. |
