ESMF_DLADIV Subroutine

subroutine ESMF_DLADIV(A, B, C, D, P, Q)

\brief \b ESMF_DLADIV performs complex division in real arithmetic, avoiding unnecessary overflow. \htmlonly Download ESMF_DLADIV + dependencies [TGZ] [ZIP] [TXT] \endhtmlonly \par Purpose:

\verbatim

ESMF_DLADIV performs complex division in real arithmetic

                  a + i*b
       p + i*q = ---------
                  c + i*d

The algorithm is due to Michael Baudin and Robert L. Smith and can be found in the paper “A Robust Complex Division in Scilab” \endverbatim \param[in] A \verbatim A is DOUBLE PRECISION \endverbatim
