scipy.special.poch

scipy.special.poch(z, m) = <ufunc 'poch'>

Rising factorial (z)_m

The Pochhammer symbol (rising factorial), is defined as

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

For positive integer m it reads

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

Parameters:

z : array_like

(int or float)

m : array_like

(int or float)

Returns:

poch : ndarray

The value of the function.
