# MatSeqAIJKron
Computes C, the Kronecker product of A and B. 
## Synopsis
```
#include "petscmat.h" 
PetscErrorCode MatSeqAIJKron(Mat A, Mat B, MatReuse reuse, Mat *C)
```

## Input Parameters

- ***A -*** left-hand side matrix
- ***B -*** right-hand side matrix
- ***reuse -*** either `MAT_INITIAL_MATRIX` or `MAT_REUSE_MATRIX`



## Output Parameter

- ***C -*** Kronecker product of A and B





## Note
`MAT_REUSE_MATRIX` can only be used when the nonzero structure of the product matrix has not changed from that last call to `MatSeqAIJKron()`.
