       dtrans - transpose and scale source matrix

       SUBROUTINE DTRANS(PLACE, SCALE, SOURCE, M, N, DEST)

       CHARACTER*1 PLACE
       INTEGER M, N
       DOUBLE PRECISION SCALE

       CHARACTER(LEN=1) :: PLACE
       INTEGER :: M, N

       REAL(8), DIMENSION(:) :: SOURCE, DEST

       SUBROUTINE TRANS_64(PLACE, SCALE, SOURCE, M, N, DEST)

   C INTERFACE
       #include <sunperf.h>

       void  dtrans(char  place,  double  scale, double *source, int m, int n,
                 double *dest);

       void dtrans_64(char place, double scale, double *source, long  m,  long
                 n, double *dest);



PURPOSE
       dtrans  scales  and  transposes the source matrix of (M, N). The result
       matrix of (N, M) is written into SOURCE when PLACE = 'I'  or  'i',  and
       DEST when PLACE = 'O' or 'o'.

         PLACE = 'I' or 'i': SOURCE = SCALE * SOURCE'

         PLACE = 'O' or 'o': DEST = SCALE * SOURCE'


ARGUMENTS
       PLACE (input)
                 Type  of  transpose.  'I' or 'i' for in-place, 'O' or 'o' for
                 out-of-place.


       SCALE (input)
                 Scale factor on the SOURCE matrix.


       SOURCE (input/output)
                 On entry, array of (M, N).  On exit, array of (N, M)  if  in-
                 place transpose; unchanged if out-of-place transpose.


       M (input)
                 Number of rows in the SOURCE matrix on input.


       N (input)
                 Number of columns in the SOURCE matrix on input.


       DEST (output)
                 Scaled  and  transposed  SOURCE matrix if out-of-place trans-
                 pose.  Not referenced if in-place transpose.
