eraTrxp

trp = ERFA.trxp(r, p)

Multiply a p-vector by the transpose of an r-matrix.

Given:

   r        double[3][3]   r-matrix
   p        double[3]      p-vector

Returned:

   trp      double[3]      r^T * p

Note:

   It is permissible for p and trp to be the same array.

Called:

   eraTr        transpose r-matrix
   eraRxp       product of r-matrix and p-vector
