DESCRIPTION SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python. It depends onmpmath, and other ...

Once you're done with the construction, you can call system.matrix() to extract the Hamiltonian matrix itself (in dense or sparse form), or use methods such as system.diagonalize() and system.free_energy() to get derived properties. Formally, the Hamiltonian operator that corresponds to the...
Parameters --- X : ndarray, shape (n_epochs, n_channels, n_channels) A set of covariance matrices to diagonalize. eps : float, defaults to 1e-6 The tolerance for stoping criterion. max_iter : int, defaults to 1000 The maximum number of iteration to reach convergence. Returns --...
