openmc.stats.Legendre

class openmc.stats.Legendre(coefficients: Sequence[float])

Probability density given by a Legendre polynomial expansion \(\sum\limits_{\ell=0}^N \frac{2\ell + 1}{2} a_\ell P_\ell(\mu)\).

Parameters:

coefficients (Iterable of Real) – Expansion coefficients \(a_\ell\). Note that the \((2\ell + 1)/2\) factor should not be included.

Variables:

coefficients (Iterable of Real) – Expansion coefficients \(a_\ell\). Note that the \((2\ell + 1)/2\) factor should not be included.

sample(n_samples=1, seed=None)

Sample the univariate distribution

Parameters:

• n_samples (int) – Number of sampled values to generate

• seed (int or None) – Initial random number seed.

Returns:

A 1-D array of sampled values

Return type:

numpy.ndarray
