Ok, I made the corrections. Thank you.

In fact, if you just want to use your interpolated fem on a vectorial problem, 
it should work as usual (I think, but I never tried) whenever your original 
fem is scalar. To make the things working for original vectorial elements, 
real_base_value and grad_base_values functions have to be adapted. But you 
have to take into account the fact that the original element can be a direct 
product of scalar element or an intrinsic vectorial element (like Raviart 
Thomas elements for instance). This is not completely obvious, in fact.

Can you describe a little bit what you expect to do with a vectorial 
interpolated fem ? May be there is a better solution than using this 
fonctionality.

Yves.
