Sparse eigenproblems are important for various applications in computer graphics. The spectrum and eigenfunctions of the Laplace-Beltrami operator, for example, are fundamental for methods in shape analysis and mesh processing. The Subspace Iteration Method is a robust solver for these problems. In...
