Add diagonal matrix format for diagonal scaling by fritzgoebel · Pull Request #580 · ginkgo-project/ginkgo

fritzgoebel · 2020-07-01T13:47:47Z

For now, Diagonal can be applied to Dense and Csr.
The normal apply does row wise scaling, the right apply does column wise scaling.

Does this pr should be merged first? After this, #563 extract_diagonal will return Diagonal not Dense

pratikvn · 2020-07-13T09:17:40Z

I think we came to a conclusion to merge this first and make the extract diagonal return a Diagonal matrix format ?

I think we have a GKO_ASSERT_IS_SQUARE_MATRIX which throws DimensionMismatch which is better suited here. But maybe you have to add a get_size() method to MatrixData.
