eraPvup

p = ERFA.pvup(dt, pv)

Update a pv-vector, discarding the velocity component.

Given:

   dt       double            time interval
   pv       double[2][3]      pv-vector

Returned:

   p        double[3]         p-vector

Notes:

  1. "Update" means "refer the position component of the vector to a new date dt time units from the existing date".

  2. The time units of dt must match those of the velocity.
