It should be a wrapper for Mat***Preallocation(). Do these exist?<br>

Hi,<br><br>i have a small problem in python. In case of matrix assembling -info says<br>me something like:<br><br>[0] MatSetUpPreallocationWarning not preallocating matrix storage<br>[0] MatAssemblyEnd_SeqAIJMatrix size: 6006 X 6006; storage space: 12084
<br>unneeded,108036 used<br>[0] MatAssemblyEnd_SeqAIJNumber of mallocs during MatSetValues() is 6006<br>[0] MatAssemblyEnd_SeqAIJMaximum nonzeros in any row is 18<br>[0] Mat_CheckInodeFound 2002 nodes of 6006. Limit used: 5. Using Inode
<br>routines<br><br>This obviously means poor behavior because of dynamical memory allocation.<br>Unfortunately, I have no idea how to preallocate memory for Mat objects in<br>python.<br>Any suggestions?<br><br>Greetings<br>
