/**

 *    <p>
 *      Parent package for common numerical analysis procedures, including root finding,
 *      function interpolation and integration. Note that optimization (i.e. minimization
 *      and maximization) is a separate top-level package.
 *    </p>
 *    <p>
 *      Function interfaces are intended to be implemented by user code to represent
 *      domain problems. The algorithms provided by the library operate on these
 *      functions to find their roots, or integrate them, or ... Functions can be multivariate
 *      or univariate, real vectorial or matrix-valued, and they can be differentiable or not.
