Question came up on IRC, and I'm curious. Given the following:
AXIOM Computer Algebra System
Version: Axiom (September 2006)
Timestamp: Saturday September 9, 2006 at 11:29:25

(1) ->
(1) -> a1 : Quaternion Fraction Integer
Type: Void
(2) -> a2 : Quaternion Fraction Integer
Type: Void
(3) -> a3 : Quaternion Fraction Integer
Type: Void
(4) -> a4 : Quaternion Fraction Integer
Type: Void
(5) -> a1
5) ->
a1 is declared as being in Quaternion Fraction Integer but has not
been given a value.
(5) -> m := matrix[[a1,a2],[a3,a4]]
5) ->
a1 is declared as being in Quaternion Fraction Integer but has not
been given a value.
(5) ->
Why isn't this allowed? I want a1->a4 to be variables without assigned
value, and I want to create a symbolic matric where all I know about
the entries is their type, in order to do general solving operations.
How would I set this up correctly in Axiom?
Cheers,
CY
