`scipy.stats._multivariate:unitary_group_frozen.init`

source: build-install/usr/lib/python3.14/site-packages/scipy/stats/_multivariate.py:4974

Signature

def __init__(self, dim = None, seed = None)

Summary

Create a frozen (U(N)) n-dimensional unitary matrix distribution.

Parameters

dim : scalar: Dimension of matrices
seed : {None, int, `numpy.random.Generator`, `numpy.random.RandomState`}, optional: If seed is None (or np.random), the numpy.random.RandomState singleton is used. If seed is an int, a new RandomState instance is used, seeded with seed. If seed is already a Generator or RandomState instance then that instance is used.

Examples

from scipy.stats import unitary_group
x = unitary_group(3)
