# PetscSpaceTensorSetSubspace
Set a space in the tensor product space 
## Synopsis
```
#include "petscfe.h" 
PetscErrorCode PetscSpaceTensorSetSubspace(PetscSpace sp, PetscInt s, PetscSpace subsp)
```

## Input Parameters

- ***sp    -*** the function space object
- ***s     -*** The space number
- ***subsp -*** the number of spaces





## Note
The name SetSubspace is misleading because it is actually setting one of the defining spaces of the tensor product space, not a Subspace of it
