4167 | /** \brief A matrix referencing a non continuous submatrix of elements given another matrix of indices. |
---|
4168 | * |
---|
4169 | * It is the most general version of any submatrices because it uses another matrix of indices to reference |
---|
4170 | * the submatrix. |
---|
4171 | * |
---|
4172 | * The matrix of indices can be of any type with the restriction that its elements must be |
---|
4173 | * type-compatible with the size_type \c of the container. In practice, the following are good candidates: |
---|
4174 | * - \c boost::numeric::ublas::indirect_array<A> where \c A can be \c int, \c size_t, \c long, etc... |
---|
4175 | * - \c boost::numeric::ublas::matrix<int> can work too (\c int can be replaced by another integer type) |
---|
4176 | * - etc... |
---|
4177 | * |
---|
4178 | * An indirect matrix can be used as a normal matrix in any expression. If the specified indirect matrix |
---|
4179 | * falls outside that of the indices of the matrix, then the \c matrix_indirect is not a well formed |
---|
4180 | * \i Matrix \i Expression and access to an element outside of indices of the matrix is \b undefined. |
---|
4181 | * |
---|
4182 | * \tparam V the type of the referenced matrix, for example \c matrix<double>) |
---|
4183 | * \tparam IA the type of index matrix. Default is \c ublas::indirect_array<> |
