NAME
       SRC/dlag2s.f

SYNOPSIS
   Functions/Subroutines
       subroutine dlag2s (m, n, a, lda, sa, ldsa, info)
           DLAG2S converts a double precision matrix to a single precision
           matrix.

Function/Subroutine Documentation
   subroutine dlag2s (integer m, integer n, double precision, dimension( lda,
       * ) a, integer lda, real, dimension( ldsa, * ) sa, integer ldsa,
       integer info)
       DLAG2S converts a double precision matrix to a single precision matrix.

       Purpose:


            DLAG2S converts a DOUBLE PRECISION matrix, A, to a SINGLE
            PRECISION matrix, SA.

            RMAX is the overflow for the SINGLE PRECISION arithmetic
            DLAG2S checks that all the entries of A are between -RMAX and
            RMAX. If not the conversion is aborted and a flag is raised.

            This is an auxiliary routine so there is no argument checking.

       Parameters
           M

                     M is INTEGER
                     The number of lines of the matrix A.  M >= 0.

           N

                     N is INTEGER
                     The number of columns of the matrix A.  N >= 0.

           A

                     A is DOUBLE PRECISION array, dimension (LDA,N)
                     On entry, the M-by-N coefficient matrix A.

           LDA

                     LDA is INTEGER
                     The leading dimension of the array A.  LDA >= max(1,M).

           SA

                     SA is REAL array, dimension (LDSA,N)
                     On exit, if INFO=0, the M-by-N coefficient matrix SA; if
                     INFO>0, the content of SA is unspecified.

           LDSA

                     LDSA is INTEGER
                     The leading dimension of the array SA.  LDSA >= max(1,M).

           INFO

                     INFO is INTEGER
                     = 0:  successful exit.
                     = 1:  an entry of the matrix A is greater than the SINGLE
                           PRECISION overflow threshold, in this case, the content
                           of SA in exit is unspecified.
