MACOPEN FILENAME opens the file or directory FILENAME using the OPEN terminal command. Similar to the WINOPEN windows function in MATLAB.

% Examples:
%
% If you have Microsoft Word installed, then
% macopen('/myDoc.docx')
% opens that file in Microsoft Word if the file exists, and errors if it doesn't.
%
% macopen('/Applications')
% opens a new Finder window, showing the contents of your /Applications folder.
