Abstract

The Continuation of Invariant Subspaces (CIS) algorithm produces a smoothly varying basis for an invariant subspace \(\mathcal{R}(s)\) of a parameter-dependent matrix A(s). In the case when A(s) is the Jacobian matrix for a system that comes from a spatial discretization of a partial differential equation, it will typically be large and sparse. Cl_matcont is a user-friendly matlab package for the study of dynamical systems and their bifurcations. We incorporate the CIS algorithm into cl_atcont to extend its functionality to large scale bifurcation computations via subspace reduction.
