The typical usage of this classes is the passing implicit maps to The typical usage of this classes is passing implicit maps to algorithms.  If a function type algorithm is called then the function type map adaptors can be used comfortable. For example let's see the The usage with class type algorithms is little bit harder. In this case the function type map adaptors can not be used, because the function map adaptors give back temporarly objects. function map adaptors give back temporary objects. \code Graph graph; @defgroup matrices Matrices @ingroup datas \brief Two dimensional data storages.
