Multidimensional arrays
==========================

TRIQS comes with a library of multidimensional arrays. 
This library, among others, allows for easy slicing, archiving and algebraic manipulations of multidimensional arrays. 
Here are a couple of simple examples showing the basic use of this class.


Declaring and printing an array
-------------------------------
.. triqs_example:: ./array_tutorial_0.cpp
Simple operations
-------------------

.. triqs_example:: ./array_tutorial_1.cpp
HDF5 Archiving
-------------------
Archiving an array into an HDF5 file is easy:

.. triqs_example:: ./array_tutorial_2.cpp
Views: ranges and slices
-------------------------
One can easily take a slice of an array to view and modify only part of the underlying data.

.. triqs_example:: ./array_tutorial_3.cpp
Matrices and vectors
-------------------------
Arrays must be distinguished from vectors and matrices, which have an algebra of their own.

.. triqs_example:: ./array_tutorial_4.cpp
Defining through a lazy expression
-----------------------------------

.. triqs_example:: ./array_tutorial_5.cpp
Linear algebra
---------------

.. triqs_example:: ./array_tutorial_6.cpp
Map and fold
-------------

.. triqs_example:: ./array_tutorial_7.cpp
