I have a list of symbols and abbreviations. Please see my code below, at the end of this question.
This code works, but I would like to have my symbols/abbreviations with a LOCATION. By this I mean, to take one of the symbols in the text and mention it for the first time with the appropriate page in the document where it was used and so on...
\chapter*{List of Symbols}
\begin{abbrv}
\item[$\textbf{A}$] a square matrix
\item[$\textbf{z}$] a vector
\end{abbrv}
\chapter*{List of Abbreviations}
\begin{abbrv}
\item[CPU] Central Processing Unit
\item[NYC] The New York City
\end{abbrv}
Any help will be appreciated.
