- Add `stim.Circuit.get_detector_coordinates`
- Add `stim.Circuit.get_final_qubit_coordinates`
- Add `stim.DetectorErrorModel.get_detecetor_coordinates`
- Rename `MatchedError` to `ExplainedError`
- Rename `match_errors` command line mode to `explain_errors
- Move `vec_pad_add_mul` to `stim::` namespace
- Make asking for coordinates of impossible detector ids an error
- Add `stim::DetectorErrorModel::final_detector_and_coord_shift`
- Re-order measurement errors to be "more complicated" than unitary errors when reducing to single errors
Example usage:
```
>>> import stim
>>> circuit = stim.Circuit('''
... # Create Bell pair.
... H 0
... CNOT 0 1
...
... # Noise.
... DEPOLARIZE1(0.01) 0
...
... # Bell basis measurement.
... CNOT 0 1
... H 0
... M 0 1
...
... # Both measurements should be False under noiseless execution.
... DETECTOR rec[-1]
... DETECTOR rec[-2]
... ''')
>>> explained_errors = circuit.explain_detector_error_model_errors(
... dem_filter=stim.DetectorErrorModel('error(1) D0 D1'),
... reduce_to_one_representative_error=True,
... )
>>> print(explained_errors[0].circuit_error_locations[0])
CircuitErrorLocation {
flipped_pauli_product: Y0
Circuit location stack trace:
(after 0 TICKs)
at instruction #3 (DEPOLARIZE1) in the circuit
at target #1 of the instruction
resolving to DEPOLARIZE1(0.01) 0
}
```
