[Octave-bug-tracker] [bug #49774] convhull doesn't accept option simplify

[Avinoam Kalma]

Follow-up Comment #3, bug #49774 (project octave):

In the script from comment#1, ks=k.

You can see the behavior of "simplify"= true in the script


xx = -3:1:3;
yy = -3:1:3;
[x,y] = meshgrid(xx,yy);
k = convhull(x,y);
ks = convhull(x,y, 'simplify', true);
save chull1.mat


chull1.mat attached,

Note that 'simplify'= true omits all the points that if we drop them, the
convex hull will not change.
In the 2D case it's simple:
if a few points are on a straight segment, the inner points are
omitted, and the end points are left.
