Eigen::UniformScaling

template<typename _Scalar>
class Eigen::UniformScaling< _Scalar >

Represents a generic uniform scaling transformation.

This is defined in the Geometry module.

#include <Eigen/Geometry>

Template Parameters

_Scalar

the scalar type, i.e., the type of the coefficients.

This class represent a uniform scaling transformation. It is the return type of Scaling(Scalar), and most of the time this is the only way it is used. In particular, this class is not aimed to be used to store a scaling transformation, but rather to make easier the constructions and updates of Transform objects.

To represent an axis aligned scaling, use the DiagonalMatrix class.

inline

Returns: *this with scalar type casted to NewScalarType

Note that if NewScalarType is equal to the current scalar type of *this then this function smartly returns a const reference to *this.

Returns: the inverse scaling

isApprox()

template<typename _Scalar >

bool Eigen::UniformScaling< _Scalar >::isApprox	(	const UniformScaling< _Scalar > &	other,
		const typename NumTraits< Scalar >::Real &	prec = `NumTraits<Scalar>::dummy_precision()`
	)		const

inline

Returns: true if *this is approximately equal to other, within the precision determined by prec.
