giac/xcas has some Maple compatibility.
It may be active if you answered Maple at xcas first run
(Choose initial configuration). You can activate it
at any time in a session using
Edit->Preferences->Cas configuration
click on Prog style choose Maple
then click OK. Run File->Save config to keep this mode
for the next sessions.
You can run simple Maple worksheet using
File->Import session->maple worksheet.
To run a text file with a Maple program, choose
File->Import session->Maple text. In Maple mode, you can also
use the read
command.
I recommend to read the section 6
(First steps) below, the main differences in the interface are :
- a new command is entered in 2-d mode in history or in 1-d
mode in the commandline
(see figure in section 6)
- if you modify one entry in the history, all commands
will be recomputed instead of just this one
- graphical commands output their graphical answer in
a separate window (click on the yellow geo button for 2-d graphs,
click on the yellow hist button to go back to history).
The graphic window is not erased
between graphical commands (that's mandatory for dynamical geometry).
Use the erase button and validate to erase the 2-d plot. Maple-like plot
commands will insert a line in the history that tells xcas
to print the plot when asked. Geometry commands will not make a print
(you must use the graph2tex() command to print a geometry figure).
- % is understood, but not %% or %%%, please use
ans(-2) or ans(-3) instead.
- The print instruction does not output in the interactive
history window but in the io (input/output) window. Use the io
or ia button to switch from interactive to input/output mode in
the history or geometry window.
The history prints
the return value of a program (following RETURN or last evaluation).
This way return value and printed value are not confused.
- Some commands of maple are not yet implemented, some other
will not return exactly the same answers, and a few require modifications
in the way arguments are entered (e.g. sum arguments should not
be quoted). Some valid maple identifiers are reserved word in xcas
(e.g. base, list) or may not be unprotected yet.
