PetscErrorCode TSRHSSplitSetIJacobian(TS ts, const char splitname[], Mat Amat, Mat Pmat, TSIJacobianFn *ijac, void *ctx)

Logically Collective

Input Parameters#

ts - the TS context obtained from TSCreate()
splitname - name of this split
Amat - (approximate) matrix to store Jacobian entries computed by f
Pmat - matrix used to compute preconditioner (usually the same as Amat)
ijac - the Jacobian evaluation routine
ctx - user-defined context for private data for the split function evaluation routine (may be NULL)
