Abstract
The Lanczos scheme for finding low-lying eigenvalues of a sparse matrix of large dimension is applied to solving the Hamiltonian formulation for and Ising spin systems in 1+1 dimensions. The location of the fixed points and the values of the critical indices are consistent with known results.
