# scipy.integrate.fixed_quad

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

  Compute a definite integral using fixed-order Gaussian quadrature.

  Description:

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

  Inputs:

  > func – a Python function or method to integrate
  >   (must accept vector inputs)

  > a – lower limit of integration b – upper limit of integration args – extra arguments to pass to function. n – order of quadrature integration.

  Outputs: (val, None)

  > val – Gaussian quadrature approximation to the integral.
