Scilab Function

scaling - affine transformation of a set of points

### Calling Sequence

  `xy1=scaling(xy,factor,[orig])`

### Parameters

- `xy1` : matrice of size (2,.).
- `xy` : matrice of size (2,.).
- `factor` : real scalar, coefficient of the linear transformation.
- `orig` : shift vector; default value is [0;0].

### Description

`scaling` performs an affine transformation on the set of points defined by the coordinates `xy` :

`xy1(:,i) = factor * xy(:,i) + orig` .
