scipy.integrate.fixed_quad¶

scipy.integrate.fixed_quad(func, a, b, args=(), n=5)¶

Compute a definite integral using fixed-order Gaussian quadrature.

Integrate func from a to b using Gaussian quadrature of order n.

Parameters :

func : callable

A Python function or method to integrate (must accept vector inputs).

a : float

Lower limit of integration.

b : float

Upper limit of integration.

args : tuple, optional

Extra arguments to pass to function, if any.

n : int, optional

Order of quadrature integration. Default is 5.

Returns :

val : float

Gaussian quadrature approximation to the integral
