Hi, I have a question about how to display the stiffness matrix in coefficient form PDE.
the essential method is adding the input matrix in my eigenvalue solver, but after running, there's a error "K is not stored."
I've checked my program, but have no idea why K is not stored. I'm looking forward your answers.
Thanks!
