# MatHIPSPARSESetFormat
Sets the storage format of `MATSEQHIPSPARSE` matrices for a particular operation. Only the `MatMult()` operation can use different GPU storage formats 
## Synopsis
```
#include "petscmat.h" 
PetscErrorCode MatHIPSPARSESetFormat(Mat A, MatHIPSPARSEFormatOperation op, MatHIPSPARSEStorageFormat format)
```
Not Collective


## Input Parameters

- ***A -*** Matrix of type `MATSEQAIJHIPSPARSE`
- ***op -*** `MatHIPSPARSEFormatOperation`. `MATSEQAIJHIPSPARSE` matrices support `MAT_HIPSPARSE_MULT` and `MAT_HIPSPARSE_ALL`. `MATMPIAIJHIPSPARSE` matrices support `MAT_HIPSPARSE_MULT_DIAG`, `MAT_HIPSPARSE_MULT_OFFDIAG`, and `MAT_HIPSPARSE_ALL`.
- ***format -*** `MatHIPSPARSEStorageFormat` (one of `MAT_HIPSPARSE_CSR`, `MAT_HIPSPARSE_ELL`, `MAT_HIPSPARSE_HYB`.)
