The gamma function is a mathematical function that extends the concept of factorial to real and complex numbers. It is defined as:
[ \Gamma(z) = \int_0^\infty t^{z-1} e^{-t} dt ]
for ( \Re(z) > 0 ) and is extended to the rest of the complex plane by analytic continuation.
Using scipy.special.gamma
The scipy.special module provides a gamma function that can be used to compute the gamma function for real or complex numbers. Here is an example of how to use it:
import numpy as npfrom scipy.special import gamma# Compute gamma function for an array of valuesvalues = [0, 0.5, 1, 5]result = gamma(values)print(result) # Output: [ inf 1.77245385 1. , 24. ]# Compute gamma function for a complex numberz = 2.5 + 1jresult_complex = gamma(z)print(result_complex) # Output: (0.77476210455108352+0.70763120437959293j)Copied!✕CopyUsing math.gamma
