d_packed_monomial
does not have limits in the number of variables it can represent. The first template parameter, T
, is the same as in packed_monomial
. The second template parameter is the (approximate) number of bits you want to devote to each exponent. So for instance if you use NBits==8
and T
an unsigned integral type, then each exponent will have a range of circa [0, 256]
(it will be less than that in reality, but same order of magnitude).
d_packed_monomial
is kind of like a vector of packed_monomial
s
d_packed_monomial
, you can access the underlying vector of T
s via the _container()
function. You can then proceed to unpack each T
value as if it was the value in a packed_monomial
. For instance:using d_type = d_packed_monomial<unsigned long, 8>;
// This is the number of exponents packed in each unsigned long stored in a d_type.
// This is a compile-time constant.
constexpr auto psize = d_type::psize;
// Create a monomial.
d_type d{....};
// Print out all exponents.
for (const auto &n : d._container()) {
k_unpacker<unsigned long> ku(n, psize);
unsigned long tmp;
for (auto j = 0u; j < psize; ++j) {
ku >> tmp;
std::cout << tmp << '\n';
}
}
psize
. That is, if psize
is 8, then the code above will print either 8, 16, 24, 32, etc... exponents.
