Hi Mattia,
Try the following to set A = cos(pi*x) in a 1-D problem.
A = gf_mesh_fem_get(MFU, 'eval', {'cos(pi * x)'});

Good morning everybody,
first of all I'd like to thank people reading and suggesting solutions
in this list: I always found a solution for my trivial problems!
I have to set a position dependent 'A' parameter in a 'generic
elliptic'
problem. I think I have to use this function and pass the 'A'
parameter
as 'V'.

contain the new parameter value. If a meshfem is given , V should hold
the field values over that meshfem (i.e. its last dimension should be

But my question is: "How to format this matrix? V"
Thanks a lot Mattia
