Please answer below, not above, as is the custom of this list.
I used them long ago. You read the help and you get it. Essentially,
they are used for transforming a set of points in 2-D from5A one reference
system to a different one, with possible affine or projection
transformation. You create a transformation matrix using maketform or
cp2tform and give this matrix as argument to either tformfwd or tforminv
depending on the transformation direction.
