Hello,
I have two 3d points on a unit sphere, which are A1(x1,y1,z1) and A2(x2,y2,z2). I want to connect A1 and A2 points and draw an arc. Then my code like this: P = [A1;A2];
plot3(P(:,1),P(:,2),P(:,3)). However, by this way, the connect line between A1 and A2 is a straight line instead of an arc. My plot like below,

Many thanks for your help in advance.
