# DMTSSetIFunction

set TS implicit function evaluation function

### Synopsis

    #include "petscts.h"
    PetscErrorCode DMTSSetIFunction(DM dm,TSIFunction func,void *ctx)

Not Collective

### Input Arguments

| dm | - DM to be used with TS
| func | - function evaluation function, see TSSetIFunction() for calling sequence
| ctx | - context for residual evaluation

### Note

TSSetFunction() is normally used, but it calls this function internally because the user context is actually associated with the DM. This makes the interface consistent regardless of whether the user interacts with a DM or not. If DM took a more central role at some later date, this could become the primary method of setting the residual.
