Hi,
Is there a way to detect a division by zero without causing
an error that returns to the maxima toplevel? It would be
useful, for instance to check for singularities at endpoints
of a numerical integration range. (Something like perl's
eval() would be great! For instance with parse_string() to
test if a string is legal maxima without causing an
exception.)
A harder question is to search for singularities (including
removable singularities) within a range. In numerical
integration, Mathematica requires a user to list
singularites in the interior of the interval, something that
RJF criticized 19 years ago, but is still the case. But
there must exist algorithms to search for them.
Regards,
John
