 Author Comment/Response Daryl Robbins 10/19/02 6:28pm I have two quick questions about Mathematica. Firstly, I am wondering how to create/draw an augmented matrix (a matrix with a line seperating it into two parts). For example: [4 5 6 | 1] [5 2 6 | 2] [3 6 3 | 2] Secondly, is there any way to come up with one possible solution to problem with infinite solutions. For example: u = {1, 2, 3}; (* any old vector *) v = {a, b, c}; Solve[Dot[u, v] == 0] I am looking for any value of v that is not the zero vector ({0, 0, 0}) that is perpendicular to u (so their dot products are equal to 0). It's easy enough to do on paper, but I can't seem to find a way to make Mathematica do it. Thank you very much. /Daryl Robbins URL: ,
