Dear all,<br>
<br>
How can I reorder a sparse matrix in Petsc?<br>
<br>
Sth like in a dirty MATLAB like pseudo-code:<br>
A = diag([1 3 4 5]);<br>
neworder = [2 4 1 3];<br>
B = A(neworder, neworder)<br>
<br>
I know I will destroy the sparsity pattern, but for my application there is no other way, the matrices should be reordered for some partitioning.<br>
<br>
