Functions

void slag2d(
    const INT              m,
    const INT              n,
    const f32*    restrict SA,
    const INT              ldsa,
          double* restrict A,
    const INT              lda,
          INT*             info
);

void slag2d(const INT m, const INT n, const f32 *restrict SA, const INT ldsa, double *restrict A, const INT lda, INT *info)

SLAG2D 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.

Parameters

in

m

The number of lines of the matrix A. m >= 0.

in

n

The number of columns of the matrix A. n >= 0.

in

SA

Real (single precision) array, dimension (ldsa, n). On entry, the M-by-N coefficient matrix SA.

in

ldsa

The leading dimension of the array SA. ldsa >= max(1, m).

out

A

Double precision array, dimension (lda, n). On exit, the M-by-N coefficient matrix A.

in

lda

The leading dimension of the array A. lda >= max(1, m).

out

info

Exit status:

• = 0: successful exit (always succeeds).
