## Synopsis
```
#include "petscmat.h" 
PetscErrorCode MatKAIJRestoreSRead(Mat A, const PetscScalar **S)
```
Not Collective


## Input Parameters

- ***A -*** the `MATKAIJ` matrix
- ***S -*** location of pointer to array obtained with `MatKAIJGetS()`





## Note
This routine zeros the array pointer to prevent accidental reuse after it has been restored.
If `NULL` is passed, it will not attempt to zero the array pointer.
