Honestly, I can find neither subclass MatSeqAIJ nor the method
setPreallocation(). I create matrix as follows:
import PETSc.Mat
K = PETSc.Mat.Mat() ## as far as i know this is the only way to create
matrix in python
K.setSizes(size, size, Size, Size)
K.setFromOptions
()
K.setType("seqaij") ## i choose matrix type here, I don't know another
way...
Where is the moment to preallocate?
It may be that they never wrapped the preallocation methods. It seems strange, but
possible. I guess I would mail Lisandro and see.
