Hi! I’m new to using NonlinearSolve.jl and trying to understand how to provide an analytical jacobian to the problem. I realize that this is unnecessary if we have autodiff in the mix since that will be enough - but in cases where I have say registered functions (and corresponding registered jacobia…

[image] askprash: df(u,p) = 2.0 .* u That’s not outputing a matrix. Did you mean Diagonal(2.0 .* u)?
