Matt,<br><br>Thank you for answering. Another question. Which functions does the PETSc call the BLAS routines to multiply those matrices?<br><br>Thanks.<br><br><div class="gmail_quote">2009/8/27 Matthew Knepley <span dir="ltr"><<a href="mailto:knepley@gmail.com">knepley@gmail.com</a>></span><br>

Good afternoon,<br><br>I am multiplying two matrices using the function MatMatMult_MPIAIJ_MPIAIJ, but I'd like to know if this function calls the BLAS routine that multiply matrices, and if yes ,where.</blockquote></div>

<br>No, this is for sparse matrices.<br><br> Matt<br> </div><div class="im"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><br>Best Regards.<br clear="all">
