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
