.PP
\fBDLAG2S\fP converts a double precision matrix to a single precision matrix\&.  
.PP
\fBPurpose: \fP
.RS 4

.PP
.nf
 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 an auxiliary routine so there is no argument checking.

.fi
.PP
.br
\fIN\fP 
.PP
.nf
          N is INTEGER
          The number of columns of the matrix A.  N >= 0.
.fi
.PP
.br
\fIA\fP 
.PP
.nf
          A is DOUBLE PRECISION array, dimension (LDA,N)
          On entry, the M-by-N coefficient matrix A.
.fi
.PP
.br
\fILDA\fP 
.PP
.nf
          LDA is INTEGER
          The leading dimension of the array A.  LDA >= max(1,M).
.fi
.PP
.br
\fISA\fP 
.PP
.nf
          SA is REAL array, dimension (LDSA,N)
          On exit, if INFO=0, the M-by-N coefficient matrix SA; if
          INFO>0, the content of SA is unspecified.
.fi
.PP
.br
\fILDSA\fP 
.PP
.nf
          LDSA is INTEGER
          The leading dimension of the array SA.  LDSA >= max(1,M).
.fi
.PP
.br
\fIINFO\fP 
.PP
.nf
          INFO is INTEGER
          = 0:  successful exit.
          = 1:  an entry of the matrix A is greater than the SINGLE
                PRECISION overflow threshold, in this case, the content
                of SA in exit is unspecified.
