NettetThe integral evaluates to $1.36 \times 10^{-9}$. Computing the same integral in Matlab and Mathematica results in a value of $1.13 \times 10^{-7}$ in each case, with no warnings or errors. This strongly suggests that the integral converges just fine, and that the problem lies in scipy's quadrature routine. Attempts at a Solution: NettetIntegration over multiple variables. Wraps quad to enable integration over multiple variables. Various options allow improved integration of discontinuous functions, as well as the use of weighted integration, and generally finer control of the integration process.
