finesse.symbols.Function.eval

Function.eval(**kwargs)

Evaluates the operation.

Parameters

subsdict, optional

Parameter substitutions can be given via an optional subs dict (mapping parameters to substituted values).

keepiterable, str

A collection of names of variables to keep as variables when evaluating.

Returns

resultnumber or array-like

The single-valued result of evaluation of the operation (if no substitutions given, or all substitutions are scalar-valued). Otherwise, if any parameter substitution was a numpy.ndarray, then a corresponding array of results.

Notes

A division by zero will return a NaN, rather than raise an exception.
