TSRHSSplitSetIJacobian#

Set the Jacobian for the split implicit function with TSARKIMEX

Synopsis#

#include "petscts.h"  
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)
