Changeset [5f59cc61a8847b7b2c949dcb672fd19650518f8d] by Jed Brown

Revision 5f59cc61a8847b7b2c949dcb672fd19650518f8d, committed by Jed Brown · January 31st, 2013 @ 12:21 AM

In old versions of sympy, A.dot(B) was a rank-2 tensor contraction. This
is no longer the case, so we need the much uglier A.vec().dot(B.vec()).
