Dear all,
I'm working with curves and I have this problem: I have sampled closed
curves and I want to find the interior part of them. I have done some
experiments using fill command but I haven't find what I'm looking for. I
try to explain you the problems that I have find by examples.
Let
t=[0:1/100:2*pi]
and
(cos(t),sin(t)) the unit circle.
If I run
fill(cos(t),sin(t));
it returns the plot of the circle with the interior part colored and it's
ok, but if I run
fill(cos(2*t),sin(2*t));
it returns only the plot of the cicle without the interior part colored.
Why? For my purpose (cos(t),sin(t)) and (cos(2*t),sin(2*t)) have the same
interior part.
I have noted that if I have a self intersect curve like two circles with no
empty intersection (but not only a point) command fill returns the plot of
the curve but the intersection of the circles is not colored. Why? For my
purpose the interior part of the two circles is the union of the internal
parts of them and not this union wthout the intersection.
How can I solve my problem? Is fill the best command I can run becouse of my
purpose?
thank you
