[Scilab-users] Answer: Is there a way, to fill the area between two non-intersecting 2d-curves with a colour?

[Heinz Nabielek]

Is there a way, to fill the area between two non-intersecting 2d-curves with a colour?

was my question from 9 November. With the help of p.muehlmann at gmail.com, here is the answer:

“xfpoly”. 

In detail, below.

Best greetings
Heinz

xfpoly(polyX, polyY,3);
