Detailed Description

template<class T>
class ns3::ValArray< T >

ValArray is a class to efficiently store 3D array.

The class is general enough to represent 1D array or 2D arrays. ValArray also provides basic algebra element-wise operations over the whole array (1D, 2D, 3D).

Main characteristics of ValArray are the following:

ValArray uses std::valarray to efficiently store data.
In general, the elements are stored in memory as a sequence of consecutive 2D arrays. The dimensions of 2D arrays are defined by numRows and numCols, while the number of 2D arrays is defined by numPages. Notice that if we set the number of pages to 1, we will have only a single 2D array. If we additionally set numRows or numCols to 1, we will have 1D array.
All 2D arrays have the same dimensions, i.e. numRows and numCols.
2D arrays are stored in column-major order, which is the default order in Eigen and Armadillo libraries, which allows a straightforward mapping of any page (2D array) within ValArray to Eigen or Armadillo matrices.

Examples of column-major order:

a) in the case of a 2D array, we will have in memory the following order of elements, assuming that the indexes are rowIndex, colIndex, pageIndex:

a000 a100 a010 a110 a020 a120.

b) in the case of a 3D array, e.g, if there are two 2D arrays of 2x3 dimensions we will have in memory the following order of elements, assuming that the indexes are rowIndex, colIndex, pageIndex:

a000 a100 a010 a110 a020 a120 a001 a101 a011 a111 a021 a121.

The access to the elements is implemented in operators:
operator (rowIndex) and operator[] (rowIndex) for 1D array (assuming colIndex=0, pageIndex=0),
operator (rowIndex,colIndex) for 2D array (assuming pageIndex=0) and
operator(rowIndex, colIndex, pageIndex) for 3D array.

Definition of ValArray as a template class allows using different numerical types as the elements of the vectors/matrices, e.g., complex numbers, double, int, etc.
