NAME

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

SYNOPSIS

       SUBROUTINE DLAT2S( UPLO, N, A, LDA, SA, LDSA, INFO )

           CHARACTER      UPLO

           INTEGER        INFO, LDA, LDSA, N

           REAL           SA( LDSA, * )

           DOUBLE         PRECISION A( LDA, * )

PURPOSE

       DLAT2S converts a DOUBLE PRECISION triangular matrix, SA, to a SINGLE PRECISION triangular
       matrix, A.
        RMAX is the overflow for the SINGLE PRECISION arithmetic
        DLAS2S 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

        UPLO    (input) CHARACTER*1
                = 'U':  A is upper triangular;
                = 'L':  A is lower triangular.

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

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

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

        SA      (output) REAL array, dimension (LDSA,N)
                Only the UPLO part of SA is referenced.  On exit, if INFO=0,
                the N-by-N coefficient matrix SA; if INFO>0, the content of
                the UPLO part 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 the UPLO part of SA in exit is unspecified.
