plot an arc between two points

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.

First get the radius of sphere....I hope center is (0,0,0). To get radius use:

Exactly! The radius of the unit sphere is 1. And the center of the sphere is (0,0,0). So can you tell me that how can I get the correct plot? Thanks so much.
