Hi!
Printing an indexed expression using an instance of the print_csrc_double
class produces invalid C code (the same syntax that is used in the tutorial
http://www.ginac.de/tutorial/Indexed-objects.html#Indexed-objects) in
ginac-1.3.7. I understand that the index class in ginac is more powerful than
the indexing facilities of the C language, but still I expected
print_csrc_double to produce valid C code simply due to its name. So I added
a few lines which handle the case of integer indices (numeric or symbolic)
stored in the idx class (patch attached).
Kind regards,
Markus
