<div dir="ltr"><div><div><div>Hi,<br><br></div>I have four global matrices: A (mxm), B (mxn), C (nxm) and D (nxn). All of these are of type MATMPIAIJ (sparse parallel matrix) created using number of global rows and columns. I want to construct an (m+n)x(m+n) global matrix called M which would have A, B, C and D as its sub-matrices in clockwise fashion starting from A at the upper-left. What can be the best way to construct M from A, B, C and D sub-matrices?<br><br></div>Thanks,<br></div>Bikash <br clear="all"><div><div><div><div><br>-- <br><div class="gmail_signature"><div dir="ltr"><div><div><div><div><font color="#666666">Bikash S.
