# RescalingTransform

RescalingTransform[{{xmin,xmax},{ymin,ymax},},{{xpmin,xpmax},}]

gives a TransformationFunction that rescales the region with coordinate ranges xmin to xmax, etc. to the region with coordinate ranges xpmin to xpmax, etc.

RescalingTransform[{{xmin,xmax},{ymin,ymax},}]

gives a TransformationFunction that rescales to the unit square, cube, etc.

## Basic Examples(2)

Rescaling the rectangle to :

This now maps {xmax,ymax} to {1,1}:

Rescaling the cube to :

This maps {xmax,ymax,zmax} to {1,1,1}:

## Scope(3)

Transforming the rectangle to the rectangle :

This transforms the midpoint in the source rectangle to the midpoint in the target rectangle:

## Properties & Relations(3)

The inverse of RescalingTransform[{{l1,u1},},{{L1,U1},}] is given by RescalingTransform[{{L1,U1},},{{l1,u1},}]:

This shows that t1 and t2 are inverses:

Rescaling transformation is a composition of scaling and translation:

Rescale provides a scalar version of RescalingTransform:
