Welcome to SpM's documentation! =============================== This is a documentation of Sparse Modeling (SpM) tool for analytical continuation. What is SpM ? ------------- A sparse-modeling tool for computing the spectral function from the imaginary-time Green function. It removes statistical errors in quantum Monte Carlo data, and performs a stable analytical continuation. The obtained spectral function fulfills the non-negativity and the sum rule. The computation is fast and free from tuning parameters. License -------------- This package is distributed under GNU General Public License version 3 (GPL v3).
