Hi Guys,
I have what should be a simple problem but what I'm sad to say I can't figure out. I have a 3-dimensional image volume. I want to view a slice of it using the slice function but can't get seem to get it. The slice should range from: size(X,1) at page 1 to 1 in the first dimension at size(X,3). (So for an example perfect cube 500x500x500, the slice would be 45degrees into the third dimension).
I've toyed with the slice function demo, but can't seem to figure out how to make it diagonal in only one dimension. Any pointers please on how to set up x,y,z is much appreciated?
Thanks! - Sean

Maybe you're looking for something like this?
% Define 3D data
[x,y,z] = meshgrid(linspace(-1,1,30));
v = x.^2 + y.^2 + z.^2;
% Define the slice plane
[xi, yi] = meshgrid(linspace(-1,1,50));
zi = xi;
% Slice it
slice(x,y,z,v,xi,yi,zi);
