geomspline
p agree to within 1000*eps in Euclidean distance. Otherwise, an open curve is
generated.
On success, c is a curve2 or curve3 object that passes through the points defined
by p. If p does not define a spline curve properly, either an error occurs or a line1,
curve2, curve3, or circ1 object is created that meets the requirements in some
way.

% Interpolate irregularly distributed point on a circle.
% First create circle data
phi=0:0.2:2*pi; phi(end)=[];
% Remove some of the points.
phi([1 3 6 7 10 20 21 25 28])=[];
p=[cos(phi);sin(phi)];
% Add some noise.
randn('state',17)
p=p+0.05*randn(size(p));
plot(p(1,:),p(2,:),'r.')
% Interpolate using uniform parameterization.
c=geomspline(p,'splinemethod','uniform','closed','on')
hold on
geomplot(c,'pointmode','off')
% Interpolate using centripetal parameterization.
