 |   * Warning : this should NOT be confused with automatic differentiation, which | 
 |   * is a different method and has its own module in Eigen : \ref | 
 |   * AutoDiff_Module. | 
 |   * | 
 |   * Currently only "Forward" and "Central" schemes are implemented. Those | 
 |   * are basic methods, and there exist some more elaborated way of | 
 |   * computing such approximates. They are implemented using both | 
 |   * proprietary and free software, and usually requires linking to an | 
 |   * external library. It is very easy for you to write a functor | 
 |   * using such software, and the purpose is quite orthogonal to what we | 
 |   * want to achieve with Eigen. | 
 |   * | 
 |   * This is why we will not provide wrappers for every great numerical | 
 |   * differentiation software that exist, but should rather stick with those | 
 |   * basic ones, that still are useful for testing. | 
 |   * | 
 |   * Also, the \ref NonLinearOptimization_Module needs this in order to | 
 |   * provide full features compatibility with the original (c)minpack | 
 |   * package. |
