Detailed Description

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

\geometry_module

Represents a generic uniform scaling transformation

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.

Member Function Documentation

◆ cast()

template<typename _Scalar >

template<typename NewScalarType >

UniformScaling< NewScalarType > Eigen::UniformScaling< _Scalar >::cast ( ) const

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.

◆ inverse()

template<typename _Scalar >

UniformScaling Eigen::UniformScaling< _Scalar >::inverse ( ) const

inline

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.
