Hi @abougouffa ,
The symbols are slightly different but the meaning is the same.
On the left side of (5.2), s is a scalar, and z_{k,j} is a 3D vector like [u,v,1]^T. When multiplying them together, we get a vector [su, sv, s]^T. One the right side, K(Ry+t) also gives a 3D vector. By comparing them, we see s is exactly the third element of K(Ry+t).
First, I would like to thank you for this book, it is really a very good resource in the subject.
I didn't understand this phrase (in chapter 5, p105)
