scipy.integrate.quadrature(func, a, b, args=(), tol=1.49e-08, rtol=1.49e-08, maxiter=50, vec_func=True, miniter=1)[source]

Compute a definite integral using fixed-tolerance Gaussian quadrature.

Integrate func from a to b using Gaussian quadrature with absolute tolerance tol.

Parameters: func : function A Python function or method to integrate. a : float Lower limit of integration. b : float Upper limit of integration. args : tuple, optional Extra arguments to pass to function. tol, rol : float, optional Iteration stops when error between last two iterates is less than tol OR the relative change is less than rtol. maxiter : int, optional Maximum order of Gaussian quadrature. vec_func : bool, optional True or False if func handles arrays as arguments (is a “vector” function). Default is True. miniter : int, optional Minimum order of Gaussian quadrature. val : float Gaussian quadrature approximation (within tolerance) to integral. err : float Difference between last two estimates of the integral.
