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.
