Objectives

In this tutorial we will optimize the main bottleneck we discovered previously - the matrix-vector product. You will learn about Ginkgo's sparse matrix formats: gko::matrix::Coo, gko::matrix::Csr and gko::matrix::Ell, and find out which one is the most suitable format for the Poisson matrix.
