What I did was the replacement of system_matrix with a function, providing 
a vmult()-function. Now I would like to add a preconditioner based on that 
function to reduce the necessary GMRES-iterations. But until now most of 
the preconditioners require a matrix for initialization. Thus I wanted to 
replace that matrix with my LinearOperator, if that is possible?
