SEOBNRv2OptimizedInterpolatorNoAmpPhase()

static UNUSED int SEOBNRv2OptimizedInterpolatorNoAmpPhase ( REAL8Array *  yin, REAL8  tinit, REAL8  deltat, UINT4  num_input_times, REAL8Array **  yout  )

This function is largely based on/copied from XLALAdaptiveRungeKutta4(), which exists inside the lal/lib/utilities/LALAdaptiveRungeKutta4.c file subroutine.

It reads in an array of timeseries that contain data not evenly spaced in time and performs cubic spline interpolations to resample the data to uniform time sampling. Interpolations use GSL's built-in routines, which recompute interpolation coefficients each time the itnerpolator is called. This can be extremely inefficient; in case of SEOBNRv4, first data points exist at very large dt, and interp. coefficients might be needlessly recomputed 10,000+ times or more. We also made the optimization that assumes the data are sampled at points monotone in time. tinit and deltat specify the desired initial time and time spacing for the output interpolated data, num_input_times denotes the number of points yin arrays are sampled in time. yout is the output array.
