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
