Examples of com.nr.interp.Curve_interp.interp()

com.nr.interp.Curve_interp.interp()
Interpolate a point on the stored curve. The point is parameterized by t, in the range [0,1]. For open curves, values of t outside this range will return extrapolations (dangerous!). For closed curves, t is periodic with period 1. @param tt @return

    target[0]=2.5*vec[0];
    target[1]=2.5*vec[1];
    target[2]=2.5*vec[2];
//    System.out.printf(target[0] << " " << target[1] << " " << target[2] << endl;
    Curve_interp myCurve = new Curve_interp(ptsin);
    double[] f=myCurve.interp(2.5/(NPTS-1));  
//    System.out.printf(f[0]/target[0] << " " << f[1]/target[1] << " " << f[2]/target[2] << endl;
    sbeps=1.e-3;
    System.out.printf("     Discrepancy (straight line): %f\n", maxel(vecsub(f,target)));
    localflag = maxel(vecsub(f,target)) > sbeps;
    globalflag = globalflag || localflag;
