Usage
Functions/Subroutines
subroutine zlag2c (m, n, a, lda, sa, ldsa, info)
ZLAG2C converts a complex double precision matrix to a complex single precision matrix.
Function/Subroutine Documentation
subroutine zlag2c (integer m, integer n, complex*16, dimension( lda, * ) a, integer lda, complex, dimension( ldsa, * ) sa, integer ldsa, integer info)
ZLAG2C converts a complex double precision matrix to a complex single precision matrix.
Purpose:
!> !> ZLAG2C converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A. !> !> RMAX is the overflow for the SINGLE PRECISION arithmetic !> ZLAG2C checks that all the entries of A are between -RMAX and !> RMAX. If not the conversion is aborted and a flag is raised. !> !> 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. !>
A
!> A is COMPLEX*16 array, dimension (LDA,N) !> On entry, the M-by-N coefficient matrix A. !>
LDA
!> LDA is INTEGER !> The leading dimension of the array A. LDA >= max(1,M). !>
SA
!> SA is COMPLEX array, dimension (LDSA,N) !> On exit, if INFO=0, the M-by-N coefficient matrix SA; if !> INFO>0, the content of SA is unspecified. !>
LDSA
!> LDSA is INTEGER !> The leading dimension of the array SA. LDSA >= max(1,M). !>
INFO
!> INFO is INTEGER !> = 0: successful exit. !> = 1: an entry of the matrix A is greater than the SINGLE !> PRECISION overflow threshold, in this case, the content !> of SA in exit is unspecified. !>
