finesse.tracing.tools.compute_abcd¶
- finesse.tracing.tools.compute_abcd(from_node=None, to_node=None, via_node=None, path=None, direction='x', symbolic=False, simplify=False, solution_name=None)[source]¶
Computes the composite ABCD matrix through a given path.
By setting the argument symbolic to true, this method will return a symbolic representation of the ABCD matrix rather than a numeric matrix.
- Parameters
- from_node
Node Node to trace from.
- to_node
Node Node to trace to.
- via_node
Node, optional Optional node to trace via.
- path
OpticalPath, optional A pre-generated path to use (produced from a call to
Model.path()).- directonstr, optional
Direction of ABCD matrix computation (can be ‘x’, for tangential plane, or ‘y’, for sagittal plane).
- symbolicbool, optional
Flag indicating whether to compute a symbolic ABCD matrix.
- simplifybool, optional
Attempt to simplify symbolic equations, can be slow for complex models
- from_node
- Returns
- out
ABCDSolution ABCD matrix solution object between the specified nodes.
