The IFISS Incompressible Flow & Iterative Solver Software package contains software
which can be run with MATLAB or Octave to create a computational laboratory for the
interactive numerical study of incompressible flow problems. It includes algorithms
for discretization by mixed finite element methods and a posteriori error estimation
of the computed solutions, together with state-of-the-art preconditioned iterative
solvers for the resulting discrete linear equation systems.
In this paper we give a flavour of the code's main features and illustrate its applicability
using several case studies. We aim to show that IFISS can be a valuable tool in both
teaching and research.
