p = ERFA.s2p(theta, phi, r)

Convert spherical polar coordinates to p-vector.

Given:

   theta   double       longitude angle (radians)
   phi     double       latitude angle (radians)
   r       double       radial distance

Returned:

   p       double[3]    Cartesian coordinates

Called:

   eraS2c       spherical coordinates to unit vector
   eraSxp       multiply p-vector by scalar
