I am using MatLab, I want to build a topographic 3D map, I am following this guide, I have been doing the steps listed on the section Draping Geoid Heights over Topography, and I do not have any trouble getting the expected result, it looks like this.

                               I have this

Now, my trouble is that I want to have a specific area, just a country not the whole world... How can I limit a specific area using coordinates in order to have a topographic 3D map that looks like this one.

                               expected result
