NAME
       dlat2s.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dlat2s (UPLO, N, A, LDA, SA, LDSA, INFO)
	   DLAT2S converts a double-precision triangular matrix to a single-precision triangular
	   matrix.

Function/Subroutine Documentation
   subroutine dlat2s (characterUPLO, integerN, double precision, dimension( lda, * )A,
       integerLDA, real, dimension( ldsa, * )SA, integerLDSA, integerINFO)
       DLAT2S converts a double-precision triangular matrix to a single-precision triangular
       matrix.

       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.

       Parameters:
	   UPLO

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

	   N

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

	   A

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

	   LDA

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

	   SA

		     SA is 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

		     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 the UPLO part of SA in exit is unspecified.
