Some question about jitter Matrix expressions??

Hi all,
I have some question in jitter ,like two video operation or matrix expressions?I read jitter recipe book and tutorials ,I can't understand the mean either.even I read this post .I can't understand @expr norm[1] how to used and how to work?
Should I read something about openGL book to understand the principle of mesh & texture on video & matrix in jitter?
Give me some suggestion
Thanks.

In other words, if you have a matrix, say created by jit.noise 1 float32 3, and you run that through jit.expr @expr norm[0], the values will be 0. 0.5 and 1.Try experimenting with small matrices and jit.print to see the result of the operations in the max window.A small example (watch the values in the max window):
