+TRIQS comes with a class called det_manip to easily perform operations on a special type of matrices 
+(see  :doc:`here  <../../reference/c++/det_manip/contents>`). 
+This library, among others, allows to easily add or remove lines or columns to the matrix, to calculate the determinant and the inverse. 
+Here are a couple of simple examples showing the basic use of this class.
