I keep getting a "not implemented" error. Have I made a simple mistake here, or is there a way around this? Thanks for the help. I haven't done much with matrix computations in Sage yet and am trying to learn my way around.
var('x,y')
a=matrix([[1,2],[-3,0]])
v=vector([x,y])
w=a*v.column()
w.norm()calc314Mon, 19 Mar 2012 10:25:19 -0500http://ask.sagemath.org/question/8804/
