x and y are the coordinates inside a CT scanner room (16x16) where the dose z has been measured
The center of the CT scanner is at (5.4, 10.3)
Mostly dose will fall off at 1/r^2 where r is the distance from the centre.
The actual measured dose is as follows.
x=[3.0, 3.9,4.5,5.4,6.0,6.8,7.7,4.7,5.5,6.25,7.1,7.6,8.5,2.9]; y=[5.35,6.8,4.5,5.95,3.7,5.1,5.65,8.3,9.8,7.4,9.0,6.7,8.1,9.3]; z=[103,2110,338,292,146,103,51,2510,88,288,242,103,144,2100];
I would like to plot a 3D plot graphically showing the staff the dose they will receive if they stand in the room at different positions during an CT fluoro procedure.
Not sure how to start.

What kind of 3D plot do you have in mind?
You have 3 sets of 14 elements each.
Easy to obtain a line in space
plot3(x,y,z)
However I'm not sure this is what you want.
For a surface, you are going to need more data. E.g. z should be a 16x16 matrix, and x,y 1x16 vectors defining the relevant grid.
