Detailed Description

template<typename Derived>
class Eigen::SolverBase< Derived >

A base class for matrix decomposition and solvers.

Template Parameters
Derivedthe actual type of the decomposition/solver.

Any matrix decomposition inheriting this base class provide the following API:

MatrixType A, b, x;
DecompositionType dec(A);
x = dec.solve(b); // solve A * x = b
x = dec.transpose().solve(b); // solve A^T * x = b
x = dec.adjoint().solve(b); // solve A' * x = b
Warning
Currently, any other usage of transpose() and adjoint() are not supported and will produce compilation errors.

Constructor & Destructor Documentation

◆ SolverBase()

template<typename Derived >
Eigen::SolverBase< Derived >::SolverBase ( )
inline

Default constructor

Member Function Documentation

◆ adjoint()

template<typename Derived >
AdjointReturnType Eigen::SolverBase< Derived >::adjoint ( ) const
inline
Returns
an expression of the adjoint of the factored matrix

A typical usage is to solve for the adjoint problem A' x = b:

x = dec.adjoint().solve(b);

For real scalar types, this function is equivalent to transpose().

transpose(), solve()

◆ derived() [1/2]

template<typename Derived >
EIGEN_DEVICE_FUNC Derived & Eigen::EigenBase< Derived >::derived ( )
inline
Returns
a reference to the derived object

◆ derived() [2/2]

template<typename Derived >
EIGEN_DEVICE_FUNC const Derived & Eigen::EigenBase< Derived >::derived ( ) const
inline
Returns
a const reference to the derived object

◆ solve()

template<typename Derived >
template<typename Rhs >
const Solve< Derived, Rhs > Eigen::SolverBase< Derived >::solve ( const MatrixBase< Rhs > &  b) const
inline
Returns
an expression of the solution x of $ A x = b $ using the current decomposition of A.

◆ transpose()

template<typename Derived >
ConstTransposeReturnType Eigen::SolverBase< Derived >::transpose ( ) const
inline
Returns
an expression of the transposed of the factored matrix.

A typical usage is to solve for the transposed problem A^T x = b:

x = dec.transpose().solve(b);
