Functions
Value	nk::linalg::isbanded (const Value &A, long lower, long upper, std::pmr::memory_resource *mr=nullptr)
	Banded structure test (tf = isbanded(A, lower, upper)).
Value	nk::linalg::isdiag (const Value &A, std::pmr::memory_resource *mr=nullptr)
	Diagonal structure (tf = isdiag(A)). True iff isbanded(A, 0, 0).
Value	nk::linalg::istril (const Value &A, std::pmr::memory_resource *mr=nullptr)
	Lower-triangular structure (tf = istril(A)).
Value	nk::linalg::istriu (const Value &A, std::pmr::memory_resource *mr=nullptr)
	Upper-triangular structure (tf = istriu(A)).
Value	nk::linalg::issymmetric (const Value &A, bool skew=false, std::pmr::memory_resource *mr=nullptr)
	Symmetry test (tf = issymmetric(A, skew)).
Value	nk::linalg::ishermitian (const Value &A, bool skew=false, std::pmr::memory_resource *mr=nullptr)
	Hermitian test (tf = ishermitian(A, skew)).
std::pair< Value, Value >	nk::linalg::bandwidth (const Value &A, std::pmr::memory_resource *mr=nullptr)
	Bandwidth pair ([lower, upper] = bandwidth(A)).
Value	nk::linalg::bandwidthOpt (const Value &A, const std::string &which, std::pmr::memory_resource *mr=nullptr)
	Single-output bandwidth selector (x = bandwidth(A, which)).
