I just noticed that the following seems okay:
sage: f(t)=matrix([t,t^3])
sage: type(f(t))
<type 'sage.symbolic.expression.Expression'>
sage: type(f(t).pyobject())
<type 'sage.matrix.matrix_symbolic_dense.Matrix_symbolic_dense'>
However, not much seems to work correctly:
sage: var('a')
a
sage: f(a)
[ t t^3]
sage: f(t=4)
[ t t^3]
How do I get f(t=3) to behave like:
sage: f(t).pyobject()(t=3)
[ 3 27]
Also, for multivariable calculus, it would extremely cool if the
following worked:
sage: f(t)=vector([t,t^2])
Traceback (most recent call last):
...
TypeError
Any suggestions on how to get it working?
Thanks,
Jason
