vector, matrix copy

[Thomas Walter <walter at pctc dot chemie dot uni-erlangen dot de>]

Hello,
there was recently a name change from 'gsl_vector_copy' to
'gsl_vector_cpy'.
I think this should be done for 'gsl_matrix_copy' too, or do I
missunderstand something.

What about adding something like
     if (dest == src)
       {
         /* Destination and source are the same, nothing to do */
	 return GSL_SUCCESS;
       }

in the copy sources.  The advantage is one can write for example
   gsl_vector_cpy (w, v)
in algorithms which can be written to work in-place and it depends on
the calling function whether one gets the result in a new workspace or
overwrites the input.

Bye
Thomas
