New question #149415 on DOLFIN:

Hello,
I'm trying to define a Function in "mult" inside a class.
However, the solver calling this mult handles the argument args[0] which I'd
like to use for defining my Function:
Function(self.V, args[0])
*** TypeError: in method 'new_Function', argument 1 of type 'dolfin::Function
const &'
When defining a PETScVector first it works:
testPETSc = PETScVector(self.V.dim())
<dolfin.cpp.PETScVector; proxy of <Swig Object of type 'boost::shared_ptr<
dolfin::PETScVector > *' at 0x3937300> >
Function(self.V, testPETSc)
Coefficient(FiniteElement('Discontinuous Lagrange', Cell('triangle', 1,
Space(2)), 0), 13)
The type of args[0] is:
self = <PETScKrylovMatrix of size 8608 x 8608>
args = (<Swig Object of type 'dolfin::PETScVector *' at 0x3909f30>, <Swig
Object of type 'dolfin::PETScVector *' at 0x39371e0>)
So, I'd like to convert the args[0] to a PETScVector and then create the
Function. Is this possible?
Thanks,
Patricia
