public class Dlag2s
- extends java.lang.Object
Following is the description from the original
Fortran source. For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.

* Purpose
* =======
*
* DLAG2S converts a DOUBLE PRECISION matrix, SA, to a SINGLE
* PRECISION matrix, A.
*
* RMAX is the overflow for the SINGLE PRECISION arithmetic
* DLAG2S checks that all the entries of A are between -RMAX and
* RMAX. If not the convertion is aborted and a flag is raised.
*
* This is a helper 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.
*
* A (input) DOUBLE PRECISION array, dimension (LDA,N)
* On entry, the M-by-N coefficient matrix A.
*
* LDA (input) INTEGER
* The leading dimension of the array A. LDA >= max(1,M).
*
* SA (output) REAL array, dimension (LDSA,N)
* On exit, if INFO=0, the M-by-N coefficient matrix SA.
*
* LDSA (input) INTEGER
* The leading dimension of the array SA. LDSA >= max(1,M).
*
* INFO (output) INTEGER
* = 0: successful exit
* > 0: if INFO = k, the (i,j) entry of the matrix A has
* overflowed when moving from DOUBLE PRECISION to SINGLE
* k is given by k = (i-1)*LDA+j
