<div class="">Another related question: If I do something like this:</div>

</div>
<div class="">double* data;</div>
<div class=""><br class="">
</div>
<div class="">// do stuff with data</div>
<div class="">data[i] = ...</div>
<div class=""><br class="">
</div>
<div class="">Mat A;</div>
<div class="">MatCreateSeqDense(...,data,..., &A);</div>
<div class=""><br class="">
</div>
<div class="">
<div class="">// do more stuff with data</div>
<div class="">data[i] = ..</div>
</div>
<div class=""><br class="">
</div>
<div class="">Now would the matrix A reflect the change (i.e updated A[i][j]) without making an explicit call to PetscObjectStateIncrease((PetscObject)A)?</div>

Hi Folks,<br class="">
<br class="">
Is there a way to get back the user allocated raw data pointer (column-major order) used in creating MatCreateSeqDense() from the Mat object?<br class="">
