%! @strong{Example}
%! @sp 1
%! Let @var{sp} be an object instantiated by @ref{dynTime}, both following syntaxes are equivalent:
%! @sp 1
%! @example
%! sp = setSize(sp,167);
%! @end example
%! or
%! @example
%! sp = sp.setSize(167);
%! @end example
%! @sp 1
%! Note that the second syntax is probably slower than the first one, and should not be used in a large loop.
%! @sp 2
%! @strong{This function is called by:}
%! @sp 2
%! @strong{This function calls:}
%!
%! @end deftypefn
