NAME

       LAPACK-3 - converts a DOUBLE PRECISION matrix, SA, to a SINGLE PRECISION matrix, A

SYNOPSIS

       SUBROUTINE DLAG2S( M, N, A, LDA, SA, LDSA, INFO )

           INTEGER        INFO, LDA, LDSA, M, N

           REAL           SA( LDSA, * )

           DOUBLE         PRECISION A( LDA, * )

PURPOSE

       DLAG2S converts a DOUBLE PRECISION matrix, SA, to a SINGLE PRECISION matrix, A.
        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 convertion is aborted and a flag is raised.
        This is an auxiliary routine so there is no argument checking.

ARGUMENTS

        M       (input) INTEGER
                The number of lines of the matrix A.  M >= 0.

        N       (input) INTEGER
                The number of columns of the matrix A.  N >= 0.

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

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

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

        INFO    (output) 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.
