LAPACK  3.6.1 LAPACK: Linear Algebra PACKage
 subroutine clag2z ( integer M, integer N, complex, dimension( ldsa, * ) SA, integer LDSA, complex*16, dimension( lda, * ) A, integer LDA, integer INFO )

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
 [in] M ``` M is INTEGER The number of lines of the matrix A. M >= 0.``` [in] N ``` N is INTEGER The number of columns of the matrix A. N >= 0.``` [in] SA ``` SA is COMPLEX array, dimension (LDSA,N) On entry, the M-by-N coefficient matrix SA.``` [in] LDSA ``` LDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M).``` [out] A ``` A is COMPLEX*16 array, dimension (LDA,N) On exit, the M-by-N coefficient matrix A.``` [in] LDA ``` LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M).``` [out] INFO ``` INFO is INTEGER = 0: successful exit```
