GAUSS User Guide x = seqa(1970,1,20); y = _isleap(x); delif(x,abs(y-1)); 1972.0000 /* Vector containing all leap years 1976.0000 between 1970 - 1989 */ 1980.0000 1984.0000 1988.0000 To calculate the days of a number of consecutive years: x = seqa(1983,1,3); y = _daypryr(x); sumc(y); 1096.0000 To add a portion of the following year: g = { 1986, 2, 23, 0 }; dy = dayinyr(g); sumc(y)+dy; 1150.0000 For more information on any of these functions see their respective pages in the command reference. 25.2.1 Timed Iterations Iterations of a program can be timed with the use of the hsec function in the following manner. 25-6
et = hsec; /* Start timer */ /* Segment of code to be timed */ et = (hsec-et)/100; /* Stop timer, convert to seconds */ A specific example is located in the tutorial section of your supplement. Time and Date In the case of a program running from one day into the next you would need to replace the hsec function with the date function. The ethsec function should be used to compute the time difference; a straight subtraction as in the previous example will not give the desired result. dstart = date; /* Start timer */ /* Segment of code to be timed */ dend = date; /* Stop timer */ dif = ethsec(dstart,dend)/100; /* Convert time difference to seconds */ 25-7 Time and Date
