Interesting that latex is easier for you. Is this because you are used to latex or because rst is doing it wrong? Thank you for your great work! Vinzent On Feb 5, 2:05 pm, Alan Bromborsky abro...@verizon.net wrote: Fabian Seoane wrote: On Wed, Feb 4, 2009 at 6:47 PM, Alan Bromborsky

Just rebuild sympy-git source and test the following: from sympy import * a=DeferredVector('a') b=DeferredVector('b') n=10 A=eye(11) a=Matrix(1,n,lambda i,j: 'a%g' %j) b=Matrix(1,n,lambda i,j: 'b%g' %j) A[0,1:]=a A[1:,0]=b.transpose() A.det() and it shows the right answer: 1 - a0*b0 - a1*b1 -
