-Brief_I/O

   VARIABLE  I/O  DESCRIPTION
   --------  ---  --------------------------------------------------
    m1        I   6x6 matrix to be transposed.
    mout      I   Transpose of m1.  mout can overwrite m1.
 
-Detailed_Input

    m1            This variable may contain any double precision 6x6
                  matrix.
 
-Detailed_Output

    mout          This variable is a double precision, 6x6 matrix which
                  contains the transpose of m1.  mout may overwrite m1.

-Parameters

   None.

-Exceptions

   Error free.

-Files

   None.

-Particulars

   This is a utility routine intended to facilitate passing state
   transformation matrices between C and Fortan.

-Examples

   Given below is one example of a matrix m1 with the output matrix
   mout which is implied by m1.
