Hi,
I have two questions concerning plot2d:
1. How do I plot a unit step?
Using if's together with plot2d doesn't seem to work:
(C16) plot2d((if (x > 1) then 1 else 0),[x,-1,1]);
MACSYMA was unable to evaluate the predicate:
x > 1
-- an error. Quitting. To debug this try DEBUGMODE(TRUE);)
2. The y-range seems to be ignored (e.g. plot2d(x,[x,-1,1],[y,-10,10]) shows
a plot with a y-range from about -1 to 1). Why is that?
Felix
