SYNOPSIS

   Functions/Subroutines
       subroutine slag2d (M, N, SA, LDSA, A, LDA, INFO)
           SLAG2D converts a single precision matrix to a double precision matrix.

Function/Subroutine Documentation

   subroutine slag2d (integerM, integerN, real, dimension( ldsa, * )SA, integerLDSA, double
       precision, dimension( lda, * )A, integerLDA, integerINFO)
       SLAG2D converts a single precision matrix to a double precision matrix.

       Purpose:

            SLAG2D converts a SINGLE PRECISION matrix, SA, to a DOUBLE
            PRECISION matrix, A.

            Note that while it is possible to overflow while converting
            from double to single, it is not possible to overflow when
            converting from single to double.

            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.

           SA

                     SA is REAL array, dimension (LDSA,N)
                     On entry, the M-by-N coefficient matrix SA.

           LDSA

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

           A

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

           LDA

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

           INFO

                     INFO is INTEGER
                     = 0:  successful exit
