A matrix-vector multiplication ${\cal M}_{ij}f_j$ is used to transform the distributions into the hydrodynamic quantities, where ${\cal M}_{ij}$ is a constant 19x19 matrix related to the choice of -$\mathbf{c}_i$. The non-conserved hydrodynamic quantities are then +$\mathbf{c}_i$. The nonconserved hydrodynamic quantities are then relaxed toward their (known) equilibrium values and are transformed back to new post-collision distributions via the inverse transformation ${\cal M}^{-1}_{ij}$.
