how to find points inside a 3d delaunayTriangulation object?

load('qs.mat')
figure; hold on
trisurf(K,s.Points(:,1),s.Points(:,2),s.Points(:,3),'FaceColor','none')
scatter3(x,y,z,20,'filled','k')
view(-30,10)

p=pointLocation(s,[x,y,z]);
f=find(~isnan(p));%index of points (x,y,z) inside

Thanks a lot, I did not know pointLocation function
