e = etime(t2,t1)
e = etime(t2,t1)
returns the time in seconds between vectors t1 and t2. The two vectors must be six elements long, in the format returned by clock:
T = [Year Month Day Hour Minute Second]Calculate how long a 2048-point real FFT takes.
x = rand(2048,1);
t = clock; fft(x); etime(clock,t)
ans =
0.4167
As currently implemented, the etime function fails across month and year boundaries. Since etime is an M-file, you can modify the code to work across these boundaries if needed.
