/** @brief class HessianLocallyLinearEmbedding used to preprocess
* data using Hessian Locally Linear Embedding algorithm as described in
*
* Donoho, D., & Grimes, C. (2003).
* Hessian eigenmaps: new tools for nonlinear dimensionality reduction.
* Proceedings of National Academy of Science (Vol. 100, pp. 5591-5596).
*
* Be sure k value is set with at least
* 1+[target dim]+1/2 [target_dim]*[1 + target dim], e.g.
* greater than 6 for target dimensionality of 2.
*
* Uses implementation from the Tapkee library.
*
* To use this converter with static interfaces please refer it by
* sg('create_converter','hlle',k);
