# DSGetArrayReal

Returns a real pointer to the internal array of \(T\) or \(D\). You MUST call `DSRestoreArrayReal()` when you no longer need to access the array.

## Synopsis

    #include "slepcds.h"
    PetscErrorCode DSGetArrayReal(DS ds,DSMatType m,PetscReal *a[])

Not Collective

## Input Parameters

- ds - the direct solver context

- m - the requested matrix

## Output Parameter

- a - pointer to the values

## Note

This function can be used only for `DS_MAT_T` and `DS_MAT_D`. These matrices always store real values, even in complex scalars, that is why the returned pointer is `PetscReal`.
