ESMF_SparseMatrixWrite Subroutine

  subroutine ESMF_SparseMatrixWrite(factorList, factorIndexList, fileName, &
    keywordEnforcer, rc)
!
! !ARGUMENTS:
    real(ESMF_KIND_R8),    intent(in)            :: factorList(:)
    integer(ESMF_KIND_I4), intent(in)            :: factorIndexList(:,:)
    character(*),          intent(in)            :: fileName
type(ESMF_KeywordEnforcer), optional:: keywordEnforcer ! must use keywords below
    integer,               intent(out), optional :: rc
!
! !DESCRIPTION:
!   Write the {\tt factorList} and {\tt factorIndexList} into a NetCDF file.
!   The data is stored in SCRIP format documented under section 
!   ~(\ref{sec:weightfileformat}).
!
!   Limitations:
!   \begin{itemize}
!     \item Only {\tt real(ESMF\_KIND\_R8) factorList} and 
!           {\tt integer(ESMF\_KIND\_I4) factorIndexList} supported.
!   \end{itemize}
!
!  The arguments are:
!  \begin{description}
!   \item[factorList]
!    The sparse matrix factors to be written.
!   \item[factorIndexList]
!    The sparse matrix sequence indices to be written.
!   \item[fileName]
!    The name of the output file to be written.
!   \item[{[rc]}]
!    Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
!  \end{description}
