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 s
Thank you

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.

France.Is there something to change in maxima source files or a
function to put in the code for reallocation of memory?? Is it
possible to put this function in a .sage file writting with python?
Thankx

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):

NameError: name 'dx' is not defined
Even when i put in the begining of my function var ("dx"), the problem
stay.
Thanks again

Helle everybody
Somebody can giv me an idea:
the function change a mathematica style to a python one
string = repr(mlist)
# Convert mathematica-style {} to python style []
string = string.replace('{','(').replace('}',')')
--> 488 return eval(string)
TypeError: '
Hi!
I'm a beginer in sage-python
I have done in my sage-python program a function which compute with
mathematica the hessian H and the linear resolution of H*B. This
function return the result X as a mathematica Element. But I can't
manipulate easily this mathematica element. How can I print this

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.
I need to co

Hello!
I'm a beginner in python and i want to use sage. But Where can i get
sage.4.0.2 for 64bits.
Thanks
