Hi,
I have a 3D array M, and I wanted to get the intersection points of M and a random line or a random plane. Can anyone give some advice?
Thanks
Jack

Thanks Walter. This is very helpful. I can see that the data is extracted and displayed. How can I access the data?

You can save the Slice into a variable which be of a class matlab.graphics. From this variable you can extract what you want.
% EXample
[X,Y,Z] = meshgrid(-2:.2:2);
V = X.*exp(-X.^2-Y.^2-Z.^2);
xslice = [-1.2,0.8,2];
yslice = [];
zslice = 0;
s = slice(X,Y,Z,V,xslice,yslice,zslice);
s
x = S(1).XData ;
y = S(1).YData ;
z = S(1).ZData ;
c = S(1).cData ;
