MATLAB: Problem with 3D plotting

surface

Hi!
Lets say I have these matrices: B=1×3 C=1×3 D=3×3 I want to have a 3D plot of D vs B-C plane. How can I do this? I read the help for the surface command but seems like I cant use it like this.

hi, 1. You can use plot3 :
 >>B=rand(3,1);
 >>C=rand(3,1);
 >>D=rand(3,3);
 >>plot3(B,C,D)
As size(D)=[3 3] then it is like you do
 >>figure, plot3(B,C,D(:,1))
 >>hold on, plot3(B,C,D(:,2))
 >>plot3(B,C,D(:,3))
 >>hold off
2.Or simply surf/mesh if D=F(B,C) :
 >>mesh(D)
 >>surf(D)
3.try other features :
 doc surfl
 doc contour
