你如何找到两点之间的相对影响？

double computeHeading(double latitude1, double longitude1, double latitude2, double longitude2) { double degToRad = PI / 180.0; double phi1 = latitude1*degToRad; double phi2 = latitude2*degToRad; double lam1 = longitude1*degToRad; double lam2 = longitude2*degToRad; double x,y; x = cos(phi2) * sin(lam2-lam1); printf(“X is %lf\n”, x); y = cos(phi1) * sin(phi2) – sin(phi1) * cos(phi2) * cos(lam2-lam1); printf(“Y […]
