NAME
SRC/slag2d.f

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 (integer m, integer n, real, dimension( ldsa, * ) sa, integer ldsa, double precision, dimension( lda, * ) a, integer lda, integer info)

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
    !>
