Overview

class finesse.simulations.basematrix.MatrixSystemSolver(matrix_type, unicode name, list nodes, FrequencyContainer optical_frequencies, dict mechanical_frequencies, dict electrical_frequencies, int num_optical_homs, bool is_signal_matrix, bool forced_refill)

Bases: object

A linear set of systems can be represented as a matrix, each equation in this system is a particular state which we want to compute. The system is solved by applying some inputs into various states, or the right hand side (RHS) vector, and solving the system.

The underlying matrix can be either a sparse or dense matrix. This class should not assume either, but merely call upon a standard matrix interface. Therefore the algorithm used for solving can varying significantly. The overall matrix is sectioned into submatricies which connect various states together.

Nodes represent a physical location in the model in which some state of the system must be computed. Some nodes can have multiple states, such as multiple optical modes.

Properties

MatrixSystemSolver.M

A weak reference to the underlying Matrix object.
