<div dir="ltr"><div>HI everybody, I have a doubt concerning how the function KSPSetComputeRHS works, because according to its prototype one of its arguments is a pointer to a function that takes a vector object as argument, not a pointer towards a vector object, so how is it able to set the rhs if the passage of the vector is done by value and not by reference ?<br>
<br></div>Another thing is the functioning of KSPSetComputeOperators. I want to set the linear system matrix and I want the preconditioning matrix to be equal, so can I just set the linar system matrix in the function that is argument of KSPSetComputeOperators, or do I need to make a matcopy in it ?<br>
