OsqpEigen::SparseMatrixHelper namespace

SparseMatrixHelper namespace is a namespace that contains helper function to handle osqp matrix.

Use it to create to update or manage an osqp sparse matrix. osqp sparse matrix in compressed-column or triplet form.

Functions

template<typename Derived> auto createOsqpSparseMatrix(const Eigen::SparseCompressedBase<Derived>& eigenSparseMatrix, csc*& osqpSparseMatrix) -> bool: Allocate an osqpSparseMatrix struct.
template<typename T> auto osqpSparseMatrixToEigenSparseMatrix(const csc*const& osqpSparseMatrix, Eigen::SparseMatrix<T>& eigenSparseMatrix) -> bool: Convert an osqp sparse matrix into an eigen sparse matrix.
template<typename T> auto osqpSparseMatrixToTriplets(const csc*const& osqpSparseMatrix, std::vector<Eigen::Triplet<T>>& tripletList) -> bool: Convert an osqp sparse matrix into a eigen triplet list.
template<typename Derived, typename T> auto eigenSparseMatrixToTriplets(const Eigen::SparseCompressedBase<Derived>& eigenSparseMatrix, std::vector<Eigen::Triplet<T>>& tripletList) -> bool: Convert an eigen sparse matrix into a eigen triplet list.

Allocate an osqpSparseMatrix struct.

Returns	a const point to the csc struct.

NOTE: c_malloc function is used to allocate memory please call c_free to deallcate memory.

Convert an osqp sparse matrix into an eigen sparse matrix.

Parameters
osqpSparseMatrix	is a constant pointer to a constant csc struct;
eigenSparseMatrix	is the eigen sparse matrix object.
Returns	a const point to the csc struct.

Convert an osqp sparse matrix into a eigen triplet list.

Parameters
osqpSparseMatrix	is reference to a constant pointer to a constant csc struct;
tripletList	is a std::vector containing the triplet.
Returns	a const point to the csc struct.

Convert an eigen sparse matrix into a eigen triplet list.

Parameters
eigenSparseMatrix	is the eigen sparse matrix object;
tripletList	is a std::vector containing the triplet.
Returns	a const point to the csc struct.
