Detailed Description

template<class B, class A = std::allocator<B>>
class Dune::block_vector_unmanaged< B, A >

An unmanaged vector of blocks.

block_vector_unmanaged extends the base_array_unmanaged by vector operations such as addition and scalar multiplication. No memory management is added.

Error checking: no error checking is provided normally. Setting the compile time switch DUNE_ISTL_WITH_CHECKING enables error checking.
