Ticket #11648 (new defect)
Contour plot cannot deal with non-real numbers
|Reported by:||eviatarbach||Owned by:||jason, was|
When trying to contour_plot a function that can return non-real numbers, such as
sage: contour_plot(log(x) + log(y), (-1000, 1000), (-1000, 1000))
the following error is returned:
TypeError: can't convert complex to float
Sage should print a warning and skip over the those points. This is the way R behaves.
