function mt = mltype(t)
% mltype  - return Matlab's datatype association
%
% FORMAT:       mt = mltype(t)
%
% Input fields:
%
%       t           either name or numeric type in Matlab
%
% Output fields:
%
%       mt          corresponding type
%
% Note: this function is rather useful for coders, not so much for
%       users...
