I am reading computer graphics. I am unable to distinguish between Non-uniform Scaling and Shear. Can someone explain the difference with two different examples?

$\begingroup$ There is in fact no difference. Consider a rectangle not aligned with the axis and apply a non-uniform scaling. What you get is a parallelogram... Conversely, any linear transformation can be seen as a combination of rotation and non-uniform scaling, by singular values decomposition of the matrix. $\endgroup$– user1703Mar 25 at 22:44
