openmc.stats.Tabular¶
- class openmc.stats.Tabular(x: Sequence[float], p: Sequence[float], interpolation: str = 'linear-linear', ignore_negative: bool = 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 (numpy.ndarray) – Tabulated values of the random variable
p (numpy.ndarray) – 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.
