Well ... that still make little sense. Variables are not protected; there is
nothing stopping you from re-assigning values, be it element-wise, row or
column-wise, or as a whole matrix. So I suspect you have a simple syntax
error.

But as you still have not shown an actualy error it remains idle speculation
on our side.

Not really. We all use these and read values from / assign values into at
will.  There are numerous examples in the archives of this mailing list, in
the unit tests, and in some of the slides from past presentations.
