C***LIBRARY   SLATEC
C***TYPE      SINGLE PRECISION (FULMAT-S, DFULMT-D)
C***AUTHOR  (UNKNOWN)
C***DESCRIPTION
C
C     DECODES A STANDARD TWO-DIMENSIONAL FORTRAN ARRAY PASSED
C     IN THE ARRAY DATTRV(IA,*).  THE ROW DIMENSION IA AND THE
C     MATRIX DIMENSIONS MRELAS AND NVARS MUST SIMULTANEOUSLY BE
C     PASSED USING THE OPTION ARRAY, PRGOPT(*).  IT IS AN ERROR
C     IF THIS DATA IS NOT PASSED TO FULMAT( ).
C     EXAMPLE-- (FOR USE TOGETHER WITH SPLP().)
C      EXTERNAL USRMAT
C      DIMENSION DATTRV(IA,*)
C      PRGOPT(01)=7
C      PRGOPT(02)=68
C      PRGOPT(03)=1
C      PRGOPT(04)=IA
C      PRGOPT(05)=MRELAS
C      PRGOPT(06)=NVARS
C      PRGOPT(07)=1
C     CALL SPLP(  ... FULMAT INSTEAD OF USRMAT...)
