# TSInterpolate

Interpolate the solution computed during the previous step to an arbitrary location in the interval

### Synopsis

    #include "petscts.h"
    PetscErrorCode TSInterpolate(TS ts,PetscReal t,Vec U)

Collective on TS

### Input Argument

| ts | - time stepping context
| t | - time to interpolate to

### Output Argument

U -state at given time

### Developer Notes

TSInterpolate() and the storing of previous steps/stages should be generalized to support delay differential equations and continuous adjoints.

### Keywords

TS, set
