jax.scipy.special.poch#
- jax.scipy.special.poch(z, m) = <jax._src.custom_derivatives.custom_jvp object>[source]#
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
