# Numerical library MADNESS provides a high-level environment for the solution of integral and differential equations in many dimensions using adaptive, fast methods with guaranteed precision based on multi-resolution analysis and novel separated representations. Useful examples can be found in the `src/examples` directory, where the use of the numerical library can be practiced by example. * `sininteg.cc`: Create a function and integrate * `hatom_energy.cc`: Compute the energy of the hydrogen atom * `heat.cc`: apply the Greens function to the heat equation * `3dharmonic.cc`: solve the 3D harmonic oscillator * `h2.cc`: solve the Hartree-Fock equations for the H2 molecule * `nonlinschro.cc`: use the KAIN solver for accelerating the solution of a system of non-linear equations * `hedft.cc`: use density functional theory
