-# Multi Array Container Library
+# Container with Native Operation Routines and Expressions (CNORXZ)
+
+(as always, the name was there before the acronym)
+
+![Image](./cnorxz_logo.png)
 
 ## Description
 
-This library provides a framework for handling multi dimensional containers. This includes the basic container class template `MultiArrayBase` and their derivates, the Range class templates on which the containers are defined, as well as some operation class templates, which allow comfortable calling of operations on the containers.
+This library provides a framework for handling multi dimensional data containers (arrays or array-like types), their meta data, and several kinds of operations on one or more of them.
 
 ## Build instructions
 
 The library can be installed by the following procedure (`gtest` required):
 
 ```bash
-git clone git@rqcd.ur.de:czimmermann/multi_array.git <SOURCE_DIR>
+git clone git@git.f3l.de:chizeta/cnorxz.git <LIBRARY_ROOT_DIR>
+mkdir <BUILD_DIR>
 cd <BUILD_DIR>
-cmake -DCMAKE_INSTALL_PREFIX:PATH=<INSTALL_DIR> <SOURCE_DIR>
+cmake -DCMAKE_INSTALL_PREFIX:PATH=<INSTALL_DIR> <LIBRARY_ROOT_DIR>
 make install
 ```
 
-## Usage and Examples
+To build the doxygen:
 
-To use the features of the libraries one has to include `multi_array_header.h` and link against the `libmultiarray.so`.
-The tools of the library are accessible within the namespace `MultiArrayTools`.
-
-### Some Terms
-
-* Ranges: A set of meta data which is mapped onto the linear position. Every container is supposed to be defined on at least one Range. In the simplest case a Range space "containes" the numbers [0,...,rangesize]. Ranges have to be created via the corresponding factory and only exist within a shared pointer. They cannot be copied. The reason is, that every operation performed on the containers, has to identify common sets of ranges, on which the containers are defined. Every range inherits the `RangeBase` class.
-
-* Indices: They can be thought of as iterators of the range space. In the special case of the `ContainerIndex` it is also an iterator over the corresponding container. The index type must be known at compile time (static polymorphism). Indices on a range can be obtained by `getIndex( range )`. For Container Indices call the `begin()` function of a `MultiArray`. Indices are crucial for defining operations.
-
-* `MultiArray<T,Ranges...>`: Contains data of type `T` and is defined on `Ranges...`.
-* `[Const]Slice<T,Ranges...>`: Views data of type `T` and acts as a MultiArray defined on `Ranges...`.
-* `FunctionalMultiArray`: Additional template argument indicating the funtion. The value at some position is then defined by the function value obtained from the meta data of the indices/ranges.
-
-On each of these types one can perform an operation by calling `operator(...)` where within the braces the corresponding indices have to be specified (see example below).
-
-### Example
-
-```c++
-
-#include "multi_array_header.h"

-mat::MultiArray<double,DRange,DRange> res1(dr1,dr2);
-mat::MultiArray<double,DRange,DRange> res2(dr1,dr2);
-
-/* get indices... */
-auto i1 = mat::getIndex( dr1 );
-auto i2 = mat::getIndex( dr2 );
-auto i3 = mat::getIndex( sr );
-auto i4 = mat::getIndex( sr );
-auto i5 = mat::getIndex( cr );
-
-i3->at(<metaString>);
-i5->at(<metaNum>);
-
-/* performs plus operation on each element in hypercube spanned by i1,i2,i4
-* and sums up resulting values by iterating over i4. i3 and i5 are fixed to the positions
-* given by the meta data above : */
-res1(i1,i2) += (ma_a(i1,i2,i4,i5) + ma_b(i4,i3)).c(i4); 
-
-/* calculates i2.meta() + i1.meta() and divide res1 at the corresponding entry by the result */
-res2(i1,i2) = res1(i1,i2) / fma(i2,i1)

+
+### Basics and Library organization
+
+This library consists of several building blocks. For simple usage, the most important building blocks are [ranges](#sec-ranges), [indices](#sec-indices) and [arrays](#sec-array-types).
+
+#### Ranges {#sec-ranges}
+
+Basically, a *range* defines a meta data space. There are several range class types, which are derived from the abstract base class `RangeBase`. Ranges can only be created by the corresponding factory and exclusively exist within a shared pointer; they cannot be copied. Available range class types are:
+
+* `CRange` : Classic one-dimensional range. The meta data space is simply given by integer numbers running from `0` to `size-1`. The range size is determined at runtime.
+
+* `URange<MetaT>` : Generic One-dimensional range. The meta data space is user defined, the meta data type is passed as template argument. The range size is determined at runtime.
+
+* `SRange<MetaT,S>` : The same as `URange`, but the range length is fixed at compile time by the template integer variable `S`.
+
+* `PRange<RangeT>` : Partial or sub-range, i.e. a user-defined subspace of another range. The type of the range must be known at compile time, the subspace can be specified at runtime.
+
+* `MRange<RangeTs...>` : Multi-dimensional range, spanned by a set of ranges. The number of ranges, as well as their types must be known at compile time.
+
+* `YRange` : The same as `MRange` but the number of ranges and their types can be specified at runtime.
+
+#### Indices {#sec-indices}
+
+For each range type there is a corresponding index type (`CIndex`, `UIndex<MetaT>`, `SIndex<MetaT,S>`, `PIndex<IndexT>`, `MIndex<IndexTs...>`, `YIndex`). They act as const iterators on the ranges and are a crucial component to define operations on containers. In contrast to the ranges, all index types must be known at compile time (static polymorphism, `IndexInterface<Index,MetaT>`). 
+
+Apart from range specific indices, there exist also special indices:
+
+* `DIndex` : Dynamic index wrapper, for the case that the index type cannot be determined at compile time.
+
+* `AIndex<T>` : Array index. Const iterators pointing to the data of an array-type object with data type `T`.
+
+* `BIndex<T>` : The same as `AIndex`, but not const.
+
+#### Array types {#sec-array-types}
+
+Arrays or array-like types contain or view datasets and are derived from `CArrayBase<T>` (const) or `ArrayBase<T>` for a given data type `T`. All array types are defined on a range, their data can be accessed or iterated over using suitable indices. The array-type actually containing data is called `MArray<T>`. Moreover, there exist array-types that do not contain data, but view the data of other arrays or at least parts of the data. These are called `CSlice<T>` (const view) or `Slice`.
+
+#### Expressions and Operations
+
+In the context of this library, *expressions* are classes representing an expression that is supposed to be executed at given points during an iteration proceedure that involves one or more indexed quantities. Each expression type must fulfill the following requirements:
+
+* There must be an implementation of `operator()` taking a multi-position argument indicating the position for the current iteration of each involved object according to its indices. The function can have an expression defined return value, which can be further processed.
+
+* There must be an implementation of `rootSteps()` taking an index ID as argument. The function should return jump sizes for each involved object corresponding to the given index.
+
+Each expression `Xpr` should be derived from the class `XprInterface<Xpr>`, where `Xpr` is a recurring template argument (static polymorphism).
+
+There are two important expression types:
+
+* *For* expressions: They represent a for loop over a given index.
+
+* *Operations*: They correspond to one or more indexed array types and given operation on or between them. If an operation handles nothing but the access to one single array, it is called *Operation* *Root*. 
+
+Example:
+```cpp
+#include "cnroxz.h"
+
+using namespace CNORZX;
+
+RangePtr r = CRangeFactory(3).create(); // [0,1,2]
+RangePtr s = CRangeFactory(5).create(); // [0,1,2,3,4]
+RangePtr t = URangeFactory<Int>(Vector<Int>{4,5,6}).create(); // [4,5,6]
+i = std::make_shared<CIndex>(r);
+j = std::make_shared<CIndex>(s);
+k = std::make_shared<UIndex<Int>>(t);
+
+MArray<Double> a(r*s*t); // 3-dim array, dimensions = [3,5,3], size = 45
+MArray<Double> b(r*t); // 2-dim array, dimensions = [3,3], size = 9
+MArray<Double> c(s*t); // 2-dim array, dimensions = [3,5], size = 15
+
+// set array element values of a,b,c here...
+
+c(j*k) += ( a(i*j*k) * b(j*k) * xpr(k) ).c(i);
+
+/* Explanation of the above line:
+
+c(j*k), a(i*j*k), b(j*k) and xpr(k) are operation roots, i.e.
+they manage access to the arrays c,a,b and the meta data space of index k
+
+The operations between the operation roots are also operations in the
+sense of this nomenclature, i.e. a(i*j*k) * b(j*k) is again an operation.
+
+The operation member function c() creates contraction, i.e. a for loop
+over the given index (i). If no further functions are specified, the values
+returned by the underlying operations are summed up for equivalent index
+combinations.
+
+The += invokes a for loop over the indices on the l.h.s.. The values returned
+by the expression on the r.h.s. are added to the l.h.s. Something similar could be done
+with a = operator. Then the values would just be assigned instead of added.
+
+*/
+
+// Equivalent C-stype for loop (if a,b,c were C-style arrays):
+
+for(size_t j = 0; j < s; ++j){
+	for(size_t k = 0; k < t; ++k){
+		int kv = k+4;
+		double x = 0;
+		// the contraction part:
+		for(size_t i = 0; i < r; ++i){
+			 x += a[i*s*t+j*t+k] * b[j*t+k] * kv;
+		}
+		c[j*t+k] += x;
+	}
+}
 
-Multithreading can be enabled by the operation class member function `par()`, which will parallelize the top loop. E.g. for the operation in the example above:
-```c++
-/* Enable multithreading for the loop over i1 */
-res1(i1,i2).par() = (ma_a(i1,i2,i4,i5) + ma_b(i4,i3)).c(i4);
 ```
-Caution: If you want to multithread operations over functional multi arrays, you have to make sure by yourself that involved functors are either static or const (const member variables).
 
-# Planned features
+More documentation will follow...
 
-Basically the structure of the operation routines allows in some cases (at least in those, where it is possible for simple c++ for loops) vectorization. So far the necessary implamentations are not done, but it is planned to enable these features.
+## Acknowledgments
 
-# Known Issues
+GitHub Doxygen Task based on work by [satu0king](https://github.com/satu0king/Github-Documentation-With-Doxygen/tree/master).
 
-I didn't care that much about error handling because of missing time. There it might happen that you declare a `MultiArray` or `Slice` and an operation on it yields a segfault because it was forgotten to instancate the underlying container. Of course, there should be some mechanism, that catches such things, but due to the afore mentioned lack of time, it has not been implemented in every case. If you encounter such problems, pleas tell me, but be aware, that I won't fix it very soon.
+I want to thank Gesina Schwalbe for creating the logo.
 
-There are unit tests, which cover the all crucial parts of this library, but probably not every special case. Hence, there is no warranty, that, if you do something fancy I didn't consider, everything works fine.
