Note that most methods work this way already. The main hole right now is
that explicit methods don't support nontrivial mass matrices. The best err

Mostly, yes. Indeed, we made 'shortcuts' such as "if the user provides no

Dear Jed,
I get it now... My confusion was due to being used to derived all scheme on the
pde, then discretizing, whereas the documentation assumes that the equation is
already discretized. I should have figured it out.
Is it right to think of the division between ODE, DAE and IMEX in the
doc

Hi,
I am trying to use TS to solve a simple transient problem in an unstructured
finite element f90 code.
1. Section 6.1.1 of the manual refers to a TSSetMatrices function that can be
used to set the RHS and LHS matrices, but I can;t find it. Is this section
outdated?
2. Since we are using uns
