Hello Marco,

support for arrays such as double[20] is built into the bindings. 
Support for dynamically allocated plain c-arrays is partly finished, 
please check the vector_view wrapper:

double *some_data = new double[ 20 ];
some_bindings_routine( ...., vector_view( some_data, 20 ), ... )

I think writing one for matrices is pretty straightforward if you look 
at the vector_view one. I think the best thing would be to add some 
wrappers and adaptors to have a more complete support for this to the 
bindings. Unfortunately I will be short on time for a couple of months.

Cheers,

Rutger
