I'm working on two versions of sage: sage4.3.1 and sage4.1.1.
The evaluation
sage_stuff = sage_eval(string,locals=dico,preparse='False') where
string contains a list of symbolic expressions, dico it's my
dictionnary of variables, gives an error type with sage4.3.1 but work
well with the version

Is it possible to have the equivalent sage expression of the following
string, by using sage_eval() or another function without getting this

Hi !
phi, v, u, Cxy are functions of (x,y). I use the command sage_eval
(string, locals = { 'E':E, 'u':u, 'v':u, 'phi'=phi, ..}). string
it's the expression. It's the only way i found for chang it to

Hi,
Thank you, the old idea you gave me to change '[' by ')' and ']' by
')' in the mathematica string is working.
I'm trying now to change the limit memory of maxima.

Hello everybody!
Thanks for your help.
I'm realizing that i'm definitely really bad in sage, perhaps i'll be
best in another life!!lol!
This is a piece of a code for changing a symbolic mathematica list
expression to a sage list expression:
def mmatosage(mma_list):

Even when i put in the begining of my function var (dx), the problem
stay.
Thanks again

Hi Viny,
Sage's mathematica support at present seems to be geared towards
sending data to mathematica and printing the results to the screen
Hi,
I have a problem of memory into maxima when it performs a symbolic
expression of an hessian matrix. This symbolic expression of the
hessian seems to be too big. My sage program is written using python.
And i want to compute the hessian matrix with mathematica 6.0 in my
sage file.

The system has 3 equations and 100 points. In my program i compute a
symbolic expression of the hessian. Is there a debugger in sage? Does
it work like gdb?
