[Axiom-math] Help

[Papy MASIALA]

Hi all,
My name is MASIALA-MAVUNGU PAPY.I usually design computer programs in Matlab to solve differential equations,optimization problem and for otherproblems involving matrix manipulations.
Now I'm using Axiom Computer Algebra to solve problems analytically.I have downloaded it from internet and I'm using it for a masters project in applied mathematics to design functions to solve optimal control problem.
It's runing on Windows XP .
Its command windows has the following header :

Trying to plot graphs , using Axiom book2,titled " The 30 year Horizon" , the graph does not come out:
For example
with the below command:
(1) -> draw(sin(x),x = 0..6) (as given in the above axiom book )
I have got the following error message:

Compiling function %D with type DoubleFloat -> DoubleFloat
Graph data being transmitted to the viewport manager...
SOCK-SEND-INT is invalid as a function.
protected-symbol-warn called with (NIL)


Below is the second example:
(1) -> draw(x**2,x=-1..1,curveColor == dark blue())(as gien in axiom book)
I have obtained following error message:

Can anybody help me to solve the problem.

when I'm using the following command
)copyright to view copyright notices.
)summary for a summary of useful system commands.
)quit to leave AXIOM and return to shell.
as given in the book , I'm getting the following message:

(2) -> quit
(2) quit
Type: Variable quit
(3) -> copyright
(3) copyright
Type: Variable copyright
(4) -> summary
(4) summary
Type: Variable summary
instead of getting what is specified in the book.
Can anybody help me to solve the problem

Thanks in advance

I'm afraid to tell you that *this* version of axiom doesn't support graphics on
MS Windows at all. You have, I think, 3 sensible possibilities:

* use VMware to run axiom in a virtual linux environment
* use colinux to do something similar
* use the native MS Windows version of FriCAS (which is a fork of axiom)

For all of these options, Bill Page & Waldek Hebisch can probably answer in
more detail. Also, you then will have access to the interactive help browser.

(2) -> quit

You have to type the closing parenthesis, which indicates that a system command
follows.

I take the oportunity for a shameless plug:

use the axiom mode for emacs for a better interactive axiom experience


good luck,

Martin

There is still no "native" MS Windows version of FriCAS that includes
graphics, although there is a version that runs under Cygwin. On
windows I prefer to use 'andLinux' (which is an Ubuntu distribution
running under colinux. I have a downloadable version that has
'andLinux' with Axiom pre-installed if you are interested. Please
check the FriCAS archives.

Bill Page.
