Comment(by burcin):
Thanks for working on this Carl.
I only read the patch, didn't test it yet. Explicitly having to use
.function() in two places bothers me:
* for each component of Piecewise
* in the call to generate_plot_points
Perhaps we should modify these to handle non function arguments more
gracefully after this change.
I understand that this might require a new syntax to construct Piecewise
objects. One option is to add a new parameter, which includes an ordered
list of variables. E.g.,
{{{
sage: Piecewise([[(0,1),x^2],[(1,2),5-x^2]] ,[x])
}}}
or
{{{
sage: f = Piecewise([[(-1,1),1/2+x-x^3 + y]],[x,y])
}}}
Comments?
