I am having a problem in understanding a notation in the book Matrix Analysis by C Meyer.
The notation of $A_{*1}$ is where I am facing problem.
Also I want a detail of Reflector....where will I get??
Help Needed!

$A_{\ast j}$ denotes the $j$-th column of $A$ (and we also denote the $i$-th row of $A$ by $A_{i\ast}$). It is a rather popular notation in linear algebra literature.
You may see Wikipedia for accounts of reflections and Householder reflections. Alternatively, consult any numerical linear algebra textbook.
