Detailed Description

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

A base class for matrix decomposition and solvers.

Template Parameters

Derived

the 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.

Member Function Documentation

adjoint()

template<typename Derived >

const 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().

See also

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 using the current decomposition of A.

transpose()

template<typename Derived >

const 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);
