呼び出し手順
realtimeinit(time_unit) realtime(t0) realtime(t)
パラメータ
- time_unit
実数.
realtime
の引数に関連する秒数- t0
decimal number: initial datetime, in
time_unit
. This meaning holds whenrealtime(…)
is called for the first time after the lastrealtimeinit(…)
. This first call sets the datetime origin and restarts the real timer.- t
実数. 日付
説明
これら2つの関数はScilabで実時間を処理する際に使用できます.
realtimeinit(time_unit)
は,
realtime
の引数 t
に
関する時間の単位を定義します.
realtime(t0)
を最初にコールした際,
カレントの日付がt0
に設定されます.
これ以降のコールrealtime(t)
では,
日付t
に達するまで待機します.
例
In the following example, in a loop, a job takes an arbitrary time, from 0 to 1.50 s. This is simulated with a sleep() of random duration. Although this period is not regular, realtime() is used to compensate and print something every 2.00 seconds:
clc tic(); realtimeinit(2.00); realtime(0); for k = 1:10 if k==1, mprintf("\nSleep for Wake-up at Wait until date\n"), end d = rand(1,1); sleep(d*1500); mprintf(' %4.2f s %5.2f s', d*1.5, toc()); realtime(k); mprintf(' %5.2f s\n', toc()); end
Sleep for Wake-up at Wait until date 0.28 s 0.57 s 2.08 s 0.03 s 2.11 s 4.08 s 1.27 s 5.34 s 6.08 s 0.11 s 6.19 s 8.08 s 1.28 s 9.36 s 10.08 s 0.02 s 10.10 s 12.08 s 0.28 s 12.36 s 14.08 s 0.74 s 14.82 s 16.08 s 1.12 s 17.20 s 18.08 s 1.41 s 19.49 s 20.08 s
