+  * 
+  * 
+  * This module provides a simplicial version of the left-looking Sparse QR decomposition. 
+  * The columns of the input matrix should be reordered to limit the fill-in during the 
+  * decomposition. Built-in methods (COLAMD, AMD) or external  methods (METIS) can be used to this end.
+  * See \link OrderingMethods_Module OrderingMethods_Module \endlink for the list 
+  * of built-in and external ordering methods.
