# MatDenseGetArrayAndMemType

gives read-write access to the array where the data for a `MATDENSE` matrix is stored

## Synopsis

    #include "petscmat.h"
    PetscErrorCode MatDenseGetArrayAndMemType(Mat A, PetscScalar **array, PetscMemType *mtype)

Logically Collective

## Input Parameter

- A - a dense matrix

## Output Parameters

- array - pointer to the data

- mtype - memory type of the returned pointer

## Note

If the matrix is of a device type such as `MATDENSECUDA`, `MATDENSEHIP`, etc., an array on device is always returned and is guaranteed to contain the matrix’s latest data.
