WitrynaLinearly implicit ODEs involve linear combinations of the first derivative of y, which are encoded in the mass matrix. Linearly implicit ODEs can always be transformed to an explicit form, y ' = M − 1 (t, y) f (t, y). However, specifying the mass matrix directly to the ODE solver avoids this transformation, which is inconvenient and can be ... Witryna19 gru 2024 · Pareschi, L.; Russo, G.
