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.

Scalar
template<typename _Scalar >
the scalar type of the coefficients
UniformScaling() [1/3]
template<typename _Scalar >
Default constructor without initialization.
UniformScaling() [2/3]
template<typename _Scalar >
Constructs and initialize a uniform scaling transformation
UniformScaling() [3/3]
template<typename _Scalar >
template<typename OtherScalarType >
Copy constructor with scalar type conversion
cast()
template<typename _Scalar >
template<typename NewScalarType >
- 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 >
- Returns
- the inverse scaling
isApprox()
template<typename _Scalar >
- Returns
-
true if *this is approximately equal to other, within the precision determined by prec.
