% PS05_MAIN this is the main m-file that runs all the way through problem
%   set 4 (including the kriging part). This program only calls other 
%   programs that do most of the work. Each of the "sub-programs" are 
%   built so that they can be run individually as well, so you can see 
%   how individual elements operate without having to wait for the co-krige
%   part to finish. However, keep in mind that some of these sub-programs
%   may need to be run at least once before the next sub-program in the 
%   sequence can be run.
