GateSet.
diff_frobenius
(otherGateSet, transformMx=None, gateWeight=1.0, spamWeight=1.0, normalize=True)¶ Compute the weighted frobenius norm of the difference between this gateset and otherGateSet.
Parameters: - otherGateSet (GateSet) – the other gate set to difference against.
- transformMx (numpy array, optional) – if not None, transform this gateset by G => inv(transformMx) * G * transformMx, for each gate matrix G (and similar for rho and E vectors) before taking the difference. This transformation is applied only for the difference and does not alter the values stored in this gateset.
- gateWeight (float, optional) – weighting factor for differences between gate elements.
- spamWeight (float, optional) – weighting factor for differences between elements of spam vectors.
- normalize (bool, optional) – if True (the default), the frobenius difference is defined by the sum of weighted squared-differences divided by the number of differences. If False, this final division is not performed.
Returns: Return type: float
