pygsti.modelmembers.term.exponentiate_terms_above_mag#

exponentiate_terms_above_mag(terms, order, postterm, cache=None, min_term_mag=None)#

Exponentiate a list of terms with magnitude above min_term_mag.

This function collects those terms of the orders given in orders. Optionally post-multiplies the single term postterm (so this term actually acts before the exponential-derived terms).

Parameters:

  • terms (list) – The list of terms to exponentiate. All these terms are considered “first order” terms.

  • order (int) – Integer specifying the order to compute.

  • postterm (RankOneTerm) – A term that is composed first (so “post” in the sense of matrix multiplication, not composition).

  • cache (dict, optional) – A cache to speedup repeated calls. Currently unused because min_term_mag is likely to be different on every call.

  • min_term_mag (float, optional) – The minimum term magnitude.

Return type:
