Comment:
Replying to [ticket:13570 startakovsky]:
> In the documentation,
http://www.sagemath.org/doc/reference/sage/matrix/constructor.html,
> it states that matrices can pass in callable objects, though there is no
example or test of this here. Is there documentation at least showing a
test of this functionality?
Yes, there is:
{{{
sage: m = matrix(QQ, 3, 3, lambda i, j: i+j); m
[0 1 2]
[1 2 3]
[2 3 4]
}}}
If not, it probably should be added, if not for the end user, at least to
ensure it doesn't break.

> [[3,2] , 3 ]
I don't think there is special support for matrices ''of'' callable
objects on which multiplication would act as function application, if that
is what you are looking for.
