## What is greenIntegrallab?

The app bundles six complementary modules. Adaptive Simpson recursion automatically concentrates work where the integrand bends sharply, reporting an estimated error budget alongside the function evaluation count. The singular-integral workflow layers an optional lower-endpoint square-root change of variables before composite Simpson quadrature, which is ideal for integrable blow-ups near a boundary. For higher-dimensional problems, tensor-product Simpson cubature integrates smooth scalar fields over rectangular domains in two or three dimensions with user-controlled grid density.
