rectify_iv_curve
(voltage, current, decimals=None)[source]¶ Sort the IV curve data, remove NaNs and negative values, and combine points with duplicate voltage.
Parameters: Returns: - voltage (numeric [V])
- current (numeric [A])
Notes
rectify_iv_curve
ensures that the IV curve lies in the first quadrant of the (voltage, current) plane. The returned IV curve:- increases in voltage
- contains no negative current or voltage values
- contains no NaNs
- contains no points with duplicate voltage values. Where voltage values are repeated, a single data point is substituted with current equal to the average of current at duplicated voltages.
