Usage

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
!>
