Synopsis#

#include "petscts.h" 
PetscErrorCode DMTSGetI2Jacobian(DM dm, TSI2Jacobian *jac, void **ctx)

Input Parameter#

  • dm - DM to be used with TS

Output Parameters#

  • jac - Jacobian evaluation function, for calling sequence see TSSetI2Jacobian()

  • ctx - context for Jacobian evaluation

Note#

TSGetI2Jacobian() is normally used, but it calls this function internally because the user context is actually associated with the DM.
