Signature

   def     rvs (    self    ,    mu    =  None   ,    kappa    =  1   ,    size    =  1   ,    random_state    =  None     )

Draw random samples from a von Mises-Fisher distribution.

mu : array_like: Mean direction of the distribution. Must be a one-dimensional unit vector of norm 1.
kappa : float: Concentration parameter. Must be positive.
size : int or tuple of ints, optional: Given a shape of, for example, (m,n,k), m*n*k samples are generated, and packed in an m-by-n-by-k arrangement. Because each sample is N-dimensional, the output shape is (m,n,k,N). If no shape is specified, a single (N-D) sample is returned.
random_state : {None, int, np.random.RandomState, np.random.Generator},: optional
Used for drawing random variates. If seed is None, the ~np.random.RandomState singleton is used. If seed is an int, a new RandomState instance is used, seeded with seed. If seed is already a RandomState or Generator instance, then that object is used. Default is None.

rvs : ndarray: Random variates of shape (size, N), where N is the dimension of the distribution.
