The tic and toc functions manipulate a single global time variable and are not suitable for internal function timing when external routines may also perform independent timing.
The timetic object rectifies this deficiency in Matlab and creates a proper object-oriented timing class.
t1 = timetic;
t2 = timetic;
The times reported by the two toc commands are precisely the times between the tic and toc commands.
Further, the timetic class extends the tic/toc paradigm by adding pause, start, and set operations to manipulate a timer.
tt = timetic;
% do some complicated output
start(t1); % restarts t1 without resetting the total elapsed time
Matlab 2008b and higher support multiple TIC TOC timers: t1 = tic; pause(1), t2 = tic; pause(2); toc(t1), toc(t2). But the commands "pause" and "start" can be useful for measuring processing time.
H1-line, descriptive help, date and author mentioned and it works.
Very useful & just what I was looking for. Please make this part of standard Matlab distribution!
