Eigen::MatrixPowerAtomic< MatrixType > Class Template Reference

#include <unsupported/Eigen/src/MatrixFunctions/MatrixPower.h>

Detailed Description

template<typename MatrixType>
class Eigen::MatrixPowerAtomic< MatrixType >

Class for computing matrix powers.

Template Parameters

MatrixType

type of the base, expected to be an instantiation of the Matrix class template.

This class is capable of computing triangular real/complex matrices raised to a power in the interval \( (-1, 1) \).

Note

Currently this class is only used by MatrixPower. One may insist that this be nested into MatrixPower. This class is here to facilitate future development of triangular matrix functions.

Public Member Functions
void	compute (ResultType &res) const
	Compute the matrix power.
	MatrixPowerAtomic (const MatrixType &T, RealScalar p)
	Constructor.

Constructor & Destructor Documentation

MatrixPowerAtomic()

template<typename MatrixType>

Eigen::MatrixPowerAtomic< MatrixType >::MatrixPowerAtomic	(	const MatrixType &	T,
		RealScalar	p )

Constructor.

Parameters

[in]	T	the base of the matrix power.
[in]	p	the exponent of the matrix power, should be in \( (-1, 1) \).

The class stores a reference to T, so it should not be changed (or destroyed) before evaluation. Only the upper triangular part of T is read.

)

const

Compute the matrix power.

Parameters

[out]

res

\( A^p \) where A and p are specified in the constructor.
