openmc.stats.Tabular¶

class openmc.stats.Tabular(x, p, interpolation='linear-linear', ignore_negative=False)[source]¶

Piecewise continuous probability distribution.

This class is used to represent a probability distribution whose density function is tabulated at specific values with a specified interpolation scheme.

Parameters

x (Iterable of float) – Tabulated values of the random variable
p (Iterable of float) – Tabulated probabilities
interpolation ({'histogram', 'linear-linear', 'linear-log', 'log-linear', 'log-log'}, optional) – Indicate whether the density function is constant between tabulated points or linearly-interpolated. Defaults to ‘linear-linear’.
ignore_negative (bool) – Ignore negative probabilities

Variables

x (Iterable of float) – Tabulated values of the random variable
p (Iterable of float) – Tabulated probabilities
interpolation ({'histogram', 'linear-linear', 'linear-log', 'log-linear', 'log-log'}, optional) – Indicate whether the density function is constant between tabulated points or linearly-interpolated.

classmethod from_xml_element(elem)[source]¶

Generate tabular distribution from an XML element

Parameters: elem (xml.etree.ElementTree.Element) – XML element
Returns: Tabular distribution generated from XML element
Return type: openmc.stats.Tabular

to_xml_element(element_name)[source]¶

Return XML representation of the tabular distribution

Parameters: element_name (str) – XML element name
Returns: element – XML element containing tabular distribution data
Return type: xml.etree.ElementTree.Element
