# slag2d(3lapack)

converts a SINGLE PRECISION matrix, SA, to a DOUBLE PRECISION matrix, A

## NAME

SLAG2D - converts a SINGLE PRECISION matrix, SA, to a DOUBLE PRECISION matrix, A

## SYNOPSIS

- SUBROUTINE SLAG2D(

  M, N, SA, LDSA, A, LDA, INFO )

- INTEGER

  INFO, LDA, LDSA, M, N

- REAL

  SA( LDSA, \* )

- DOUBLE

  PRECISION A( LDA, \* )

## PURPOSE

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.

## ARGUMENTS

- M (input) INTEGER

  The number of lines of the matrix A.  M \>= 0.

- N (input) INTEGER

  The number of columns of the matrix A.  N \>= 0.

- SA (input) REAL array, dimension (LDSA,N)

  On entry, the M-by-N coefficient matrix SA.

- LDSA (input) INTEGER

  The leading dimension of the array SA.  LDSA \>= max(1,M).

- A (output) DOUBLE PRECISION array, dimension (LDA,N)

  On exit, the M-by-N coefficient matrix A.

- LDA (input) INTEGER

  The leading dimension of the array A.  LDA \>= max(1,M).

- INFO (output) INTEGER

  \= 0:  successful exit ========= End of SLAG2D
