sort_sweep_arrays

plasmapy.analysis.swept_langmuir.helpers.sort_sweep_arrays(

voltage: ndarray,

current: ndarray,

voltage_order: Literal['ascending', 'descending'] = 'ascending',

) → tuple[ndarray, ndarray]

Sort the swept langmuir voltage and current traces to ensure the voltage array is either monotonically increasing or decreasing.

Parameters:

• voltage (numpy.ndarray) – 1D numpy.ndarray representing the voltage of the swept Langmuir trace. No units are assumed or checked, but values should be in volts.

• current (numpy.ndarray) – 1D numpy.ndarray representing the current of the swept Langmuir trace. Values should start from a negative ion-saturation current and increase to a positive electron-saturation current. No units are assumed or checked, but values should be in amperes.

• voltage_order (str) – Either 'ascending' or 'descending' to indicate how the voltage array should be sorted. (DEFAULT: 'ascending')

Returns:

• voltage (numpy.ndarray) – Sorted voltage array.

• current (numpy.ndarray) – Matched current array to the sorted voltage array.
