I have a 1201x1201 dataset, and I'm looking to remove all values outside my range (A-B). It will be used in a contour3 and surfc.
Here's the relevant section of code:
[X,Y] = meshgrid (105:1/1200:106,-7.25:1/1200:-6.25);
axis equal
% z = s( s>=200 & s<=500 ); - the code I've been trying to make work, but this makes my 1201x1202 double a 45221x1 double, so won't plot with contour3
contour3(X,Y,z)
surfc(X,Y,z, 'edgecolor', 'none');
's' is the original 1201x1201 dataset that i want to remove all values outside the (A-B) range from.

Alternatively, I'd like to be able to keep the data, but highlight the values in my range (A-B)

EDIT:
I've found a different method that just adjusts the range displayed and highlighted, but still provides the required outcome on my 3d plot.
caxis([A B])

s = sort(randn(128, 160));
mask = s < -1.5 | s > 2.2;
Al = double(~mask); %need 1 for visible, 0 for invisible
surf(s, 'edgecolor', 'none', 'alphadata', Al, 'facecolor', 'interp', 'facealpha', 'interp')

I seem to be having trouble getting this to work the way I expect. I will get back to it after I have some sleep.

No worries Walter,
I've found an easier method that suits my needs anyway. Instead of editing the data directly and opening a can of worms there, I've just changed the way it's displayed using caxis
Best, and thank you for your help
