Multi-dimensional array of type T.
This structure is used to define a multidimensional array of type T. The number of dimensions can be specified when constructing an object and can be altered anytime by using methods like resize(const size_array &, const T).
The simpliest way to access an array_nd element is by using operator() and specifying the offset on each dimension, like this:
int i = a(2, 3, 2)
An array_nd inherites all the functionality the array class provides, which means that it can also be indexed as an one-dimensional array using the array subscript operator: []. Keep in mind that in array_nd the elements are stored in column-major order like Fortran and Matlab and not like C. So, the offset is computed like this:
offset = row + column*NUMROWS
| const T& ivl::array_nd< T, data::normal_image< N, DERIVED_INFO > >::operator() | ( | const array< size_t, S > & | indx | ) | const [inline] |
Selects a single, const element of the array, using a size_array for the coordinates.
| T& ivl::array_nd< T, data::normal_image< N, DERIVED_INFO > >::operator() | ( | const array< size_t, S > & | indx | ) | [inline] |
Selects a single, mutable element of the array, using a size_array for the coordinates.
