    NAME
         dtrans - transpose and scale source matrix
    
         SUBROUTINE DTRANS(PLACE, SCALE, SOURCE, N1, N2, DEST)
    
         CHARACTER*1       PLACE
    
         INTEGER           N1, N2
    
         DOUBLE PRECISION  SCALE, SOURCE(N1, N2), DEST(N2, N1)
    
    
    
         #include <sunperf.h>
    
         void dtrans(char place, double scale,  double  *source,  int
                   n1, int n2, double *dest) ;
    
    PURPOSE
         DTRANS scales and transposes the source matrix.  The N2 x N1
         result  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) CHARACTER*1
                   Type of transpose.  'I' or 'i' for  in-place,  'O'
                   or 'o' for out-of-place.
    
         SCALE     (input) DOUBLE PRECISION
                   Scale factor on the SOURCE matrix.
    
         SOURCE    (input/output) DOUBLE PRECISION array of dimension
                   (N1, N2) on input.  DOUBLE PRECISION array of (N2,
                   N1) on output if in-place transpose.
    
         N1        (input) INTEGER
                   Number of rows in the SOURCE matrix on input.
    
         N2        (input) INTEGER
                   Number of columns in the SOURCE matrix on input.
    
         DEST      (output) DOUBLE PRECISION array of dimension  (N2,
                   N1).
                   Scaled and transposed  SOURCE  matrix  if  out-of-
                   place transpose.  Not referenced if in-place tran-
                   spose.
