Data Structures
struct	qpalm::alloc::ladel_sparse_matrix_deleter

Namespaces
namespace	qpalm
namespace	qpalm::alloc
	RAII-based wrappers for the allocation and deallocation functions of the C API.

Typedefs
using	qpalm::index_t = Eigen::Index
	Index types for vectors and matrices.
using	qpalm::sp_index_t = ladel_int
	Index type for sparse matrices representation.
using	qpalm::sparse_mat_t = Eigen::SparseMatrix< c_float, Eigen::ColMajor, sp_index_t >
	Owning sparse matrix type.
using	qpalm::sparse_mat_view_t = Eigen::Map< const sparse_mat_t >
	Read-only view on a sparse matrix.
using	qpalm::sparse_mat_ref_t = Eigen::Ref< const sparse_mat_t >
	Read-only reference to a sparse matrix.
using	qpalm::triplet_t = Eigen::Triplet< c_float, sp_index_t >
	Type for (row, column, value) triplets for initializing sparse matrices.
using	qpalm::vec_t = Eigen::Matrix< c_float, Eigen::Dynamic, 1 >
	Owning dense vector type.
using	qpalm::borrowed_vec_t = Eigen::Map< vec_t >
	Borrowed dense vector type (vector view).
using	qpalm::const_borrowed_vec_t = Eigen::Map< const vec_t >
	Read-only borrowed dense vector type (vector view).
using	qpalm::ref_vec_t = Eigen::Ref< vec_t >
	Reference to a dense vector (vector view).
using	qpalm::const_ref_vec_t = Eigen::Ref< const vec_t >
	Read-only reference to a dense vector (vector view).
using	qpalm::ladel_sparse_matrix_ptr = std::unique_ptr< ladel_sparse_matrix, alloc::ladel_sparse_matrix_deleter >
	Smart pointer that automatically cleans up an owning ladel_sparse_matrix object.

Functions
ladel_sparse_matrix	qpalm::eigen_to_ladel (sparse_mat_t &mat, ladel_int symmetry=UNSYMMETRIC)
	Convert an Eigen sparse matrix to a LADEL sparse matrix, without creating a copy.
ladel_sparse_matrix_ptr	qpalm::ladel_sparse_create (index_t rows, index_t cols, index_t nnz, ladel_int symmetry, bool values=true, bool nonzeros=false)
	Create an LADEL sparse matrix of the given dimensions.
ladel_sparse_matrix_ptr	qpalm::eigen_to_ladel_copy (const sparse_mat_ref_t &mat, ladel_int symmetry=UNSYMMETRIC)
	Similar to eigen_to_ladel, but creates a copy of all data, in such a way that the returned matrix is completely decoupled from mat, and such that it can be reallocated and deallocated by the ladel_sparse_free and similar functions.
