Can I get an .stl from a spreadsheet?

I have a spreadsheet with coordinate data (lat/long) and height for the surface and the bed of a glacier. I'm looking to take this data and convert it to an .stl geometry file that I can use for modeling in other programs like COMSOL or Elmer/Ice. I have been able to plot the data using boundaryFacets and trisurf to visually get a good geometry, but how do I transfer that to an .stl?
What I've tried:
iso2mesh (surf2stl command) "wrote 0 facets" when I tried surf2stl('GeoSTL',X,Y,Z);
Using delaunayTriangulation and tetramesh gives me a shape that is not similar enough to my glacier to use.
Attached is my code and an arbitrary set of coordinates and depths to represent a glacier.

Hi Darshan,
When I try surf2stl the program runs, but the output file is nonexistent (it "wrote 0 facets" like I stated above). Am I missing something with that command?

Hi Kate,
surf2stl is one of the several submissions in MATLAB File Exchange on MATLAB Central which is a forum for our product users to interact, exchange information and knowledge, without MathWorks' involvement. Feel free to contact the author of this submission directly for specific questions about the implementation.
