TSComputeRHSHessianProductFunctionUP

Runs the user-defined vector-Hessian-vector product function for Gup.

Synopsis

#include <petscts.h>  
PetscErrorCode TSComputeRHSHessianProductFunctionUP(TS ts, PetscReal t, Vec U, Vec Vl[], Vec Vr, Vec VHV[])

Collective

Input Parameters

• ts - The TS context obtained from TSCreate()

• t - the time

• U - the solution at which to compute the Hessian product

• Vl - the array of input vectors to be multiplied with the Hessian from the left

• Vr - the input vector to be multiplied with the Hessian from the right

Output Parameter

• VHV - the array of output vectors that store the Hessian product

Note

TSComputeRHSHessianProductFunctionUP() is typically used for sensitivity implementation, so most users would not generally call this routine themselves.
