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.
NN is INTEGER The number of columns of the matrix A. N >= 0.
SASA is REAL array, dimension (LDSA,N) On entry, the M-by-N coefficient matrix SA.
LDSALDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M).
AA is DOUBLE PRECISION array, dimension (LDA,N) On exit, the M-by-N coefficient matrix A.
LDALDA is INTEGER The leading dimension of the array A. LDA >= max(1,M).
INFOINFO is INTEGER = 0: successful exit
