Hi everybody,

I'm using Maple 9.5 on a mandriva station to do some analysis for my PhD. In the end, I get a plot with 2 curves : one is continuous, and the other isn't (it's a kind of Heaviside).

I didn't find a way to do a proper plot, including greek symbols, and formulas in the legends with maple... For this reason, I decided to export the results from my plot to a file containing on each line couples (x, y) and then plot it properly with another tool (gnuplot...).

At first, I thought of including in a single file my different curves, putting on each line (x, y1, y2, ...). I abandonned that idea because I realized that the number of point used for a plot could change depending on the function.

My problem is that when the function is discontinuous (let's say Heaviside(x)), if I try to collect the data into A by :

a:=plot(Heaviside(x), x=-1..1);
A:= op(1, op(1, a));

then, I get only the points from -1 to 0... But not the second part... How can I get everything in? I tried to add "discont = true" into the plot, but it didn't changed anything!

Anyone has an idea?

And the second problem is that I can't explicitly and precisely fix the number of points. if I say numpoints = 200, then it'll take 211 for some function, and if I say 211 points, then it'll take 222 points, etc..

Any idea for that too?

Thanks a lot!
