Methods for Integrating Functions

  odeint        -- Integrate ordinary differential equations.
  quad          -- General purpose integration.
  dblquad       -- General purpose double integration.
  tplquad       -- General purpose triple integration.
  gauss_quad    -- Integrate func(x) using Gaussian quadrature of order n.
  gauss_quadtol -- Integrate with given tolerance using Gaussian quadrature.

  See the orthogonal module (integrate.orthogonal) for Gaussian
     quadrature roots and weights.
