Hi everyone, I am trying to use the KLU method as linear solver for solving an ODE problem using Sundials. I have tried to apply it to the CVODE_BDF solver for a simple problem, the rober equation. However, when I provide the sparsity pattern determined from the Jacobian function, that I also prov…

You have to add the diagonal to it since it’s I - gamma*J
