clag2z
Converts a complex single precision matrix to a complex double precision matrix.
Syntax
call clag2z( m, n, sa, ldsa, a, lda, info )

Description
This routine converts a complex single precision matrix SA to a complex 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.
Input Parameters
- m
-
INTEGER. The number of lines of the matrix A (m≥ 0).
- n
-
INTEGER. The number of columns in the matrix A (n≥ 0).
- ldsa
-
INTEGER. The leading dimension of the array sa; ldsa≥ max(1, m).
- a
-
DOUBLE PRECISION array, DIMENSION (lda, n).
On entry, contains the m-by-n coefficient matrix A.
- lda
-
INTEGER. The leading dimension of the array a; lda≥ max(1, m).
Output Parameters
- sa
-
REAL array, DIMENSION (ldsa, n).
On exit, contains the m-by-n coefficient matrix SA.
- info
-
INTEGER.
If info = 0, the execution is successful.
