tic

Start a timer.

Syntax

tic
tStart = tic

Description

Records the current time. Pair with toc to measure elapsed wall-clock time. With a return value, returns a timer ID that can be passed to toc later — useful for nested or concurrent timing.

Examples

tic; pause(2); toc           % prints '~2.0s'
t1 = tic; ... toc(t1)        % nested timing
