TIC

Purpose:

Starts the interval timer.

TIC

Nothing, the interval timer is started.

tic;fft(w1);b=toc;

sprintf("FFT execution time %g seconds", b);

prints the approximate time required to calculate and display the FFT of W1.

W1: gnorm(1024*32, 1)

W2: tic;fft(w1);label(strnum(toc))

W2 is labeled with the approximate time to calculate the FFT of W1.
