% This interface can be used for any mex interface function using the
% pattern:
%   Construction -    obj = mexfun('new',         ...)
%   Destruction -           mexfun('delete', obj)
%   Other methods - [...] = mexfun('method', obj, ...)
% The standard interface avoids the need to write a specific interface
% class for each mex file.
