%           - arg3 is for program use only

% matinterrogator will display the initial arrays in a .mat file (maximum of
% 40).  Initializing matinterrogator in the command window will simply pop
% up a selection window for users to choose the .mat file they want to
% interogate.  DataOut will be released when at least one array is choosen
% for export or if matinterrogator is canceled or closed.  
%
% OpenFile  - The desired file that the user wants to interogate.
%    n      - User specified maximum number of arrays to be choosen and
%           exported.  Defaulted to max 40.
