TaoTermCreateSolutionVec

Create a solution vector for a TaoTerm

Synopsis

#include "petsctao.h" 
PetscErrorCode TaoTermCreateSolutionVec(TaoTerm term, Vec *solution)

Collective

Input Parameter

• term - a TaoTerm

Output Parameter

• solution - a compatible solution vector for term

Note

Before a TaoTerm can create a solution vector, you must do one of the following:

• Call TaoTermSetSolutionSizes() to describe the size and parallel layout of a solution vector.

• Call TaoTermSetSolutionLayout() to directly set PetscLayouts for the solution vector.

• Call TaoTermSetSolutionTemplate() to set the solution vector spaces to match existing Vec.

• If the TaoTerm is a TAOTERMSHELL, you can call TaoTermShellSetCreateSolutionVec() to use your own code for creating vectors.

You can also call TaoTermSetSolutionVecType() to set the type of vector created (e.g. VECCUDA).
