## Detailed Description

### template<class T, class L, class A>
class boost::numeric::ublas::vector_of_vector< T, L, A >

Rows or columns are not stored into contiguous chunks of memory but data inside rows (or columns) are. Orientation and storage can also be specified, otherwise a row major and unbounded arrays are used. The data is stored as a vector of vectors, meaning that rows or columns might not be stored into contiguous chunks of memory. Orientation and storage can also be specified, otherwise a row major and unbounded arrays are used. The storage type defaults to `unbounded_array<unbounded_array<T>>` and orientation is `row_major`. It is not required by the storage to initialize elements of the matrix. For a -dimensional matrix and , every element is mapped to the -th element of the container for row major orientation or the -th element of the container for column major orientation.

Template Parameters:

  | T | the type of object stored in the matrix (like double, float, complex, etc...)
  | L | the storage organization. It can be either `row_major` or `column_major`. By default it is `row_major`
  | A | the type of Storage array. By default, it is an <unbounder_array<T>>
