Just one small comment :
I would use <e> (element) instead of <c>. It is not really a column.
Doing this you could also store the transposed matrix just by exchanging
rows and columns.
It might also be a good idea to add a index attribute to <r>, <c>, and
<e> (lets think of sparse matrices):

<matrix default="0">
        <r index="1"> <e index="1">1.0</e> </r>
        <r index="2"> <e index="2">1.0</e> </r>
</matrix>

==

  1  0
 
  0  1
 

This would also show the handling of attributes.


I did not check all the code but this seems to be nice.


Cheers,
Henning
