Re: [Getfem-users] Question on Preconditioners

Hi Yves:

I tried what you suggest below:

> typedef gmm::row_matrix< gmm::wsvector<complex<double> > > mymatrixtype;
> mymatrixtype C(N2,N2);
> gmm::diagonal_precond<mymatrixtype>  P();
>
> // ...
> ... fill C
> // ...
>
> P.build_with(C);
>

But I get the following error:

error: request for member ‘build_with’ in ‘P’, which is of non-class type
‘gmm::diagonal_precond<gmm::row_matrix<gmm::wsvector<std::complex<double>
> > > ()()’

Could you help with this one?
