  abstract =     "Given a regular matrix pencil $\lambda B-A$ and a
                 positively oriented contour $\gamma$ in the complex
                 plane, the spectral dichotomy methods applied to
                 $\lambda B-A$ and $\gamma$ consist in determining
                 whether $\lambda B-A$ possesses eigenvalues on or in
                 a neighborhood of $\gamma$. When no such eigenvalues
                 exist, these methods compute iteratively the spectral
                 projector $P$ onto the right deflating subspace of
                 $\lambda B-A$ associated with the eigenvalues
                 inside/outside $\gamma$. The computation of the
                 projector is accompanied by the spectral norm $||H||$
                 of a Hermitian positive definite matrix $H$ called the
                 dichotomy condition number, which indicates the
                 numerical quality of the spectral projector $P$. The
                 smaller $||H||$ is, the better this quality. This
                 article presents a MATLAB program ({\tt specdicho})
                 implementing the main types of spectral dichotomy where
                 $\gamma$ is a circle, an ellipse, the imaginary axis or
                 a parabola.",
