How do I graph this plane with three points?

How do I graph the plane that contains the points P1=(1,2,3), P2=(1,2,1) and P3=(2,1,0) while taking p=(p1+p2+p3)/3?

[Amit]

what you mean by 'while taking p=(p1+p2+p3)/3?'? The plane can be defined by 3 points. Am I missing something?

[Anna]

well the question basically asks to graph and then it adds take initial p to be equal to (p1+p2+p3)/3

you can use geometric construction with meshgrid function or use patch function as follows :

 patch([1 1 2],[2 2 1],[3 1 0],0.5), view(30,20)
