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 : AXIOM Computer Algebra System Version of Monday January 17, 2005 at 22:31:38 ---------------------------------------------------------------------------- Issue )copyright to view copyright notices. Issue )summary for a summary of useful system commands. Issue )quit to leave AXIOM and return to shell. ---------------------------------------------------------------------------- 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... >> System error: 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: Loading C:/Documents and Settings/0612025N/My Documents/axiom/mnt/windows/algebra/ FST.o for domain FortranScalarType Loading C:/Documents and Settings/0612025N/My Documents/axiom/mnt/windows/algebra/ FT.o for domain FortranType Loading C:/Documents and Settings/0612025N/My Documents/axiom/mnt/windows/algebra/ SYMS.o for domain TheSymbolTable Loading C:/Documents and Settings/0612025N/My Documents/axiom/mnt/windows/algebra/ SYMTAB.o for domain SymbolTable Loading C:/Documents and Settings/0612025N/My Documents/axiom/mnt/windows/algebra/ TABLE.o for domain Table Loading C:/Documents and Settings/0612025N/My Documents/axiom/mnt/windows/algebra/ HASHTBL.o for domain HashTable Loading C:/Documents and Settings/0612025N/My Documents/axiom/mnt/windows/algebra/ INTABL.o for domain InnerTable Compiling function %F with type DoubleFloat -> DoubleFloat Graph data being transmitted to the viewport manager... >> System error: SOCK-SEND-INT is invalid as a function. protected-symbol-warn called with (NIL) 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
