1CLAG2Z ‐ a COMPLEX SINGLE PRECISION matrix, SA, to a COMPLEX DOU‐
2BLE PRECISION matrix, A SUBROUTINE CLAG2Z( M,  N,  SA,  LDSA,  A,
3LDA, INFO)
4    INTEGER INFO,LDA,LDSA,M,N
5    COMPLEX SA(LDSA,*)
6    COMPLEX*16  A(LDA,*)  CLAG2Z converts a COMPLEX SINGLE PRECI‐
7SION matrix, SA, to a COMPLEX DOUBLE PRECISION matrix, A.

9Note that while it is possible to overflow while converting  from
10double  to single, it is not possible to overflow when converting
11from single to double.
12
13This is a helper routine so there is no argument checking.
14
15M       (input) INTEGER The number of lines of the matrix  A.   M
16>=  0.   N       (input) INTEGER The number of columns of the ma‐
17trix A.  N >= 0.  SA      (output) REAL array, dimension (LDSA,N)
18On exit, the M‐by‐N coefficient matrix SA.  LDSA    (input) INTE‐
19GER The leading dimension of the array SA.  LDSA >= max(1,M).   A
20(input)  DOUBLE  PRECISION array, dimension (LDA,N) On entry, the
21M‐by‐N coefficient matrix A.  LDA     (input) INTEGER The leading
22dimension of the array A.  LDA >= max(1,M).  INFO    (output) IN‐
