slag2d
Converts a single precision matrix to a double precision matrix.
Syntax
call slag2d( m, n, sa, ldsa, a, lda, info )

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