NAME
       ctrans - transpose and scale source matrix

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

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

       SUBROUTINE CTRANS_64(PLACE, SCALE, SOURCE, M, N, DEST)

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

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

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

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

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

   C INTERFACE
       #include <sunperf.h>

       void  ctrans(char place, complex *scale, complex *source, int m, int n,
		 complex *dest);

       void ctrans_64(char place, complex *scale,  complex  *source,  long  m,
		 long n, complex *dest);

PURPOSE
       ctrans  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. 'I' is default.

       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.
