Pochhammer symbol.

LAX-backend implementation of scipy.special.poch().

The JAX version only accepts positive and real inputs.

Original docstring below.

The Pochhammer symbol (rising factorial) is defined as

\[(z)_m = \frac{\Gamma(z + m)}{\Gamma(z)}\]

For positive integer m it reads

\[(z)_m = z (z + 1) ... (z + m - 1)\]

See [dlmf] for more details.

Parameters:
  • z (array_like) – Real-valued arguments.

  • m (array_like) – Real-valued arguments.

Returns:

The value of the function.

Return type:

scalar or ndarray
