NAME
       strans - transpose and scale source matrix


SYNOPSIS
       SUBROUTINE STRANS(PLACE, SCALE, SOURCE, M, N, DEST)

       CHARACTER*1 PLACE
       INTEGER M, N
       REAL SCALE
       REAL SOURCE(*), DEST(*)

       SUBROUTINE STRANS_64(PLACE, SCALE, SOURCE, M, N, DEST)

       CHARACTER*1 PLACE
       INTEGER*8 M, N
       REAL SCALE
       REAL SOURCE(*), DEST(*)




   F95 INTERFACE
       SUBROUTINE TRANS(PLACE, SCALE, SOURCE, M, N, DEST)

       CHARACTER(LEN=1) :: PLACE
       INTEGER :: M, N
       REAL :: SCALE
       REAL, DIMENSION(:) :: SOURCE, DEST

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

       CHARACTER(LEN=1) :: PLACE
       INTEGER(8) :: M, N
       REAL :: SCALE
       REAL, DIMENSION(:) :: SOURCE, DEST




   C INTERFACE
       #include <sunperf.h>

       void strans(char place, float scale, float *source, int m, int n, float
                 *dest);

       void strans_64(char place, float scale, float *source, long m, long  n,
                 float *dest);



PURPOSE
       strans  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.
