You should say which Sage version you are using, and also give the
complete code. In Sage 7.4 I get this:
sage: var('x1','x2')
(x1, x2)
sage: a1=vector([76,83])
sage: b1=62
sage: x=vector([x1,x2])
sage: f1=b1-a1.dot_product(x)
sage: f1
-76*x1 - 83*x2 + 62
which looks good. Perhaps you mistyped
Hi all!
In my code, I have a multivariate polynomial with a sign symbol which
doesn't return the correct result. I.e.
The code snippet is as follows:
sage: f1=b1-a1.dot_product(x)
a1 is a vector with values (76, 83), b1 is scalar with value 62, x is a
vecto
