Why a matrix formulation in the first place We want to solve the instationary Stokes equations, but a PDE that carries a time derivative cannot be handed to a stationary linear solver directly. The...
The whole of mechanics can be summarized in a single bracket. — paraphrasing the spirit of Hamilton and Jacobi. In classical mechanics every observable lives on the phase space, the space of state...
Solving a Linear System We begin with a deceptively simple question that every undergraduate student encounters in their first linear algebra course: solving the linear system #m...
