<br>
I found that MatCreateRedundantMatrix does not support dense matrices.<br>
<br>
This causes the following problem: I cannot use CISS eigensolver from <br>
SLEPC with dense matrices with parallelization over quadrature points.<br>
<br>
Is it possible for you to add this support?<br>
<br>
Thank you,<br>
