示例1: calcSpacedDaysHours
void Ambient::calcSpacedDaysHours(double lat, double lon, double tmz, int nday, double delta_hr, vector<vector<double> > &utime, vector<int> &uday){
//Method taken from PTGen code (Wagner 2008 thesis)
double pi = PI;
uday.resize(nday);

ntstep(nday),
ntstep_day(nday);
vector<double>
noons(nday),
hours(nday);
DateTime DT;
int month, dom;
for(int i=0; i<nday; i++){
//Calculate the day number - The days are evenly distributed over the cosine wave of the year
uday[i] = 355 - (int)floor(acos(-1.+2.*i/(float)(nday-1))/pi*(float)(355-172));
DT.hours_to_date(uday[i]*24 +12., month, dom);
DT.SetHour(12);
DT.SetDate(2011, month, dom);

Ambient::calcDaytimeHours(hrs, lat*D2R, lon*D2R, tmz, DT);
noons.at(i) = (hrs[0]+hrs[1])/2.;
//shorten the time by 0.9 so we don't get stuff really close to the horizon
ntstep[i] = (int)floor( (hrs[1]-noons.at(i))*.9/delta_hr );
//For the calculated day, determine the solar declination angle and the number of daylight hours
//delta[i] = asin(23.45*D2R*cos((float)(uday[i]-173)*D2R));

//Store the day and time in the utime array

}

DT.SetMinute(int(min));
DT.SetSecond(int(sec));
