 |  *      Parent package for common numerical analysis procedures, including root finding, | 
 |  *      function interpolation and integration. Note that optimization (i.e. minimization |

 |  *      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. |
