does not create any timers. tic does the equivalent of
function current_time = tic
global tic_latest_time
current_time = now();
if nargout == 0
tic_latest_time = current_time;
end
and toc does the equivalent of
function elapsed_time = toc(tic_time)
global tic_latest_time;
current_time = now();
if nargin > 0
elapsed_time = current_time - tic_time;
else
elapsed_time = current_time - tic_latest_time;
end
except that a 64 bit integer timer is used instead of now(), and the resulting 64 bit difference is scaled into seconds.
