# 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()`.
