SLAG2D(1) LAPACK PROTOTYPE auxiliary routine (version 3.1.2) SLAG2D(1)NAME
SLAG2D - converts a SINGLE PRECISION matrix, SA, to a DOUBLE PRECISION
matrix, A
SYNOPSIS
SUBROUTINE SLAG2D( M, N, SA, LDSA, A, LDA, INFO )
INTEGER INFO, LDA, LDSA, M, N
REAL SA( LDSA, * )
DOUBLE PRECISION A( LDA, * )
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.
ARGUMENTS
M (input) INTEGER
The number of lines of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
SA (input) REAL array, dimension (LDSA,N)
On entry, the M-by-N coefficient matrix SA.
LDSA (input) INTEGER
The leading dimension of the array SA. LDSA >= max(1,M).
A (output) DOUBLE PRECISION array, dimension (LDA,N)
On exit, the M-by-N coefficient matrix A.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
INFO (output) INTEGER
= 0: successful exit ========= End of SLAG2D
