3d surface plot

3d surface plot

3d surface plot

(OP)
Hello,
I was wondering if someone can help me with this problem. I would like to plot a 3d surface plot of 3 variables. Like in the attached image. Whatever I try I can't seem get it to work. Two of the variables are ok but the third doesn't plot properly. I've got a matrix 3 columns wide and I would like the surface to go through the point described by the coordinates of each row. I seem to remember being able to do this with Matlab years ago when I was at university but now I can't make it work.
Any help would be greatly appreciated.
Thanks
George  

RE: 3d surface plot

You can use your matrix in its form if its arranged in [x,y,z] presumably. The function surfc.m plots a 3d surface of a specified matrix.
For example if you have a matrix made up of vectors:
X=[1 2 3 4 5 6 7 8 9]; Y=[4 5 6 7 1 2 3 7 8]; Z=[5 5 5 5 5 5 5 5 5];
C=[X;Y;Z];
surfc(C)

This will give you a 3d surface plot of your matrix in Cartesian coordinates.

Good luck,
