Detailed Description

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

Proxy for the matrix power of some matrix (expression).

Template Parameters

Derived type of the base, a matrix (expression).

This class holds the arguments to the matrix power until it is assigned or evaluated for some other reason (so the argument should not be changed in the meantime). It is the return type of MatrixBase::pow() and related functions and most of the time this is the only way it is used.

Constructor & Destructor Documentation

template<typename Derived>

Eigen::MatrixComplexPowerReturnValue< Derived >::MatrixComplexPowerReturnValue	(	const Derived &	A,
		const ComplexScalar &	p
	)

inline

Constructor.

Parameters

[in]	A	Matrix (expression), the base of the matrix power.
[in]	p	complex scalar, the exponent of the matrix power.

template<typename Derived>

template<typename ResultType >

void Eigen::MatrixComplexPowerReturnValue< Derived >::evalTo ( ResultType & res ) const

inline

Compute the matrix power.

Because p is complex, $ A^p $ is simply evaluated as $\exp(p \log(A))$ .

Parameters

[out] result where A and p are as in the constructor.
