finesse.simulations.graph.tools.expression_tuple_to_symbolic¶

finesse.simulations.graph.tools.expression_tuple_to_symbolic(expr, optical_equations)[source]¶

Converts an expression tuple to a symbolic expression using the provided optical equations.

Parameters

exprtuple: The expression tuple to be converted.
optical_equationsdict: A dictionary containing the optical equations.

Returns

finesse.symbols.Symbol: The simplified symbolic expression.

Notes

This function recursively converts an expression tuple into a symbolic expression using the provided optical equations. The expression tuple can contain operators such as ‘+’ and ‘*’, and operands that are either symbols or values. The optical equations dictionary maps symbols to their corresponding symbolic expressions.

Examples

>>> from finesse.symbols import Variable
>>> optical_equations = {'a': Variable('a'), 'b': Variable('b')}
>>> expr = ('+', ('*', 'a', 2), ('*', 'b', 3))
>>> expression_tuple_to_symbolic(expr, optical_equations)
2*a + 3*b
