I try to get PetscScalar array from CUSPARRAY as follows:<br>
<br>
CUSPARRAY *cusparray;<br>
PetscScalar *abc;<br>
<br>
abc = VecCUSPCastToRawPtr(*cusparray);<br>
<br>
std::cout << abc[0];<br>

However, there comes a segmentation violation error. Any opinions are welcome. Thanks.<br></blockquote><div><br></div><div style="">Aren't these device pointers?</div><div style=""><br></div><div style=""> Matt</div><div> </div>
