I am looking at IRdMatrixfDisp Interface. What do they mean by Shear?

Re: Shear
Here's a pretty good example Shell1850:
http://cs.fit.edu/~wds/classes/cse5255/ ... shear.html"
In a sense, it's a form of non-uniform scaling.
If you scale a cube Uniformly, for example, then you end up with a larger cube.
But if you Shear a cube, say, along the z-axis, then you end up with a larger cube that is stretched
in the x and y axes.
I believe that is a correct statement. Please correct me if I am wrong.
