Parameters

m	Matrix to update.
b	Vector values to write into one column.
row	First destination row.
col	Destination column.

vector()

template<std::size_t SIZE, std::size_t ROWS, std::size_t COLS, concepts::scalar scalar_t, template< typename, std::size_t > class array_t>

auto detray::algebra::storage::block_getter::vector ( const matrix< array_t, scalar_t, ROWS, COLS > & m, const std::size_t row, const std::size_t col ) const

constexprnoexcept
