Details:

It has always been a minor irritation for me in MATLAB that the "toc" command
errors out when called before "tic". It prevents the use of this one-liner
when timing loops.

++
for k = 1:10

   pause(1); % do some work
   fprintf('Pass %i: ',k); toc; tic

end
--

Just putting it out there as a possible divergence from MATLAB to default to
the start of time (0).

++
function t = toc(varargin)

% stop toc from erroring out if called before tic.

if nargin==0
    varargin{1} = uint64(0);
end

if nargout==0
    builtin('toc',varargin{:});
else
    t = builtin('toc',varargin{:});
end
--verbatin--
