Functions/Subroutines

subroutine clag2z (M, N, SA, LDSA, A, LDA, INFO)
CLAG2Z converts a complex single precision matrix to a complex double precision matrix.

Function/Subroutine Documentation

subroutine clag2z (integerM, integerN, complex, dimension( ldsa, * )SA, integerLDSA, complex*16, dimension( lda, * )A, integerLDA, integerINFO)

CLAG2Z converts a complex single precision matrix to a complex double precision matrix.

Purpose:

 CLAG2Z converts a COMPLEX matrix, SA, to a COMPLEX*16 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 COMPLEX 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 COMPLEX*16 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
