AffineTransform

AffineTransform[m]
gives a TransformationFunction that represents an affine transform that maps r to .
AffineTransform
gives an affine transform that maps r to .
MORE INFORMATION
  • For ordinary affine transforms in dimensions, m is an × matrix.
  • AffineTransform in general supports × matrices for transformations in dimensions.

Many other geometric transformations are a special case of affine transform:
In turn, an affine transformation is a special case of a linear-fractional transformation:
The composition of affine transforms is an affine transform:
