Classification scope and review notes

Electrochemical models with complex-valued equivalent-circuit impedance. The main verifies resistor and capacitor impedances and their series combination against direct complex formulas at four angular frequencies. Kinetics and parameter estimation are not covered. A4 classifies the complex arithmetic interface, not an electrochemistry-specific GAMS class.

Package dependencies

Resolved GitHub repositories used by the verified playground build, combining direct and indirect dependencies. This list does not describe internal module dependencies or native system libraries.

Reviewed procedures

These mappings have pinned source evidence. A checked package example may exercise only some of them; source review is not a numerical benchmark.

A4

A4: verified

Derivatives / callbacks: not applicable

Electrochemical models with complex-valued equivalent-circuit impedance. The main verifies resistor and capacitor impedances and their series combination against direct complex formulas at four angular frequencies. Kinetics and parameter estimation are not covered. A4 classifies the complex arithmetic interface, not an electrochemistry-specific GAMS class. Dedicated A4 consumer checks R, C and L at 216 frequency cases over 12 parameter sets, with finite complex results, status/message checks and normalized closed-form errors. Series RLC resonance and parallel RC combinations are formed by the driver, not a package circuit solver. Nonideal elements, fitting, kinetics and exceptional inputs are not verified.
