scaling¶

affine transformation of a set of points

Calling Sequence¶

xy1=scaling(xy,scalingFactor,[orig])

:xy1 matrice of size (2,.). : :xy matrice of size (2,.). : :scalingFactor real scalar, coefficient of the linear

transformation.

: :orig shift vector; default value is [0;0]. :

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

xy1(:,i) = scalingFactor * (xy(:,i) - orig) + orig.
