scipy.integrate.fixed_quad(func, a, b, args=(), n=5)[source]¶ 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). If integrating a vector-valued function, the returned array must have shape
(..., len(x)).- 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
- none : None
Statically returned value of None
