+`matrix.skeleton` is a `PGF/TikZ` library that simplifies working with multiple matrix nodes.
+To do so, `matrix.skeleton` correctly aligns groups of nodes with the content of the whole matrix.
+Furthermore, `matrix.skeleton` provides rows and columns for easy styling.
+
+For example, the following picture is easily typeset:
+
+![Example](example.pdf)
+
+with this simple code:
+
+```TeX
+\documentclass[tikz]{standalone}
+
+\usetikzlibrary{matrix.skeleton}
+
+\begin{document}
+ \begin{tikzpicture}
+ \matrix (m) [matrix of math nodes,
+ style odd rows on layer={background}{fill=black!25}] {
+ 1 & \frac{\frac{16}{2}}{4} & 3 \\
+ 4.0000001 & 5 & 6 \\
+ 7 & 8 & 9 \\
+ 10 & 11 & 12 \\
+ 13 & 14 & 15 \\
+ };
+ \fitandstyle{(m-cell-1-1) (m-cell-2-2)}{draw=red, fill=red!25, opacity=0.5}
+ \end{tikzpicture}
+\end{document}

+\section{Introduction}
+
+The \TikZ \code{matrix} library places nodes on a grid.
+However, this grid is discarded after the nodes have been placed.
+As a result, certain constructions involving multiple nodes become cumbersome.
+The following two examples highlight some of the difficulties.
+
+\subsection{Alignment Issues with \code{fit}}
+
+The \code{fit} library is used to highlight a subset of nodes in a matrix.
+If all the nodes in the matrix have the same dimension, as in~\cref{fig:highlighting_identical_dimensions}, \code{fit} produces the desired output.
+

+\end{subfigure}
+
+\caption{Highlighting in a matrix with nodes of identical dimensions}
+\label{fig:highlighting_identical_dimensions}
+\end{figure}
+
+However, if the nodes have different heights and widths, as illustrated in~\cref{fig:highlighting_different_dimensions}, some alignment issues arise.
+

+\caption{Highlighting in a matrix with nodes of different dimensions}
+\label{fig:highlighting_different_dimensions}
+\end{figure}
+
+These problems can be addressed using \code{minimum width} and \code{minimum height}.
+However, adjusting manually these parameters in every matrix is a waste of time.
+
+The \code{matrix.skeleton} library provides a clean solution through the use of nodes called~\code{cells}.
+These \code{cells} and other skeleton nodes are described in~\cref{sec:skeleton}.
+
+\subsection{Working with Rows and Columns}
+
+The readability of a matrix can sometimes be improved by adding a background on every other row.
+This simple task is not easily achievable with \code{matrix} alone.
+The style \code{every odd column} only affects the nodes of the said columns.
+There is no real column object to work with.
+
+The \code{matrix.skeleton} library provides \TikZ styles to achieve this goal easily.
+These styles are described in~\cref{sec:styling}
+
+\section{Skeleton}
+\label{sec:skeleton}
+
+\subsection{Nodes}
+
+\code{matrix.skeleton} works by positioning a set of nodes to recreate the \code{matrix} grid.
+The eight types of such nodes are illustrated in~\cref{fig:skeleton_nodes}.
+
+\begin{figure}[h]
+\centering

+\end{tikzpicture}
+\caption{\textcolor{yellow!80!orange}{Tiling cell}, \textcolor{red!50}{tiling row}, and \textcolor{green!60}{tiling column}}
+\end{subfigure}
+\caption{Skeleton nodes}
+\label{fig:skeleton_nodes}
+\end{figure}
+
+\subsection{Using \code{matrix.skeleton}}
+
+The recommended way of using \code{matrix.skeleton} is through \TikZ.
+First, load the library with:
+\begin{verbatim}
+ \usetikzlibrary{matrix.skeleton}
+\end{verbatim}
+Then add an option to your matrix:
+\begin{verbatim}
+ \matrix (m) [label skeleton] {...};
+\end{verbatim}
+This creates a set of nodes that can be used for styling.
+For example, the nodes illustrated in~\cref{fig:skeleton_nodes} are named: \code{m-cell-1-1}, \code{m-row-2}, \code{m-column-3}, \code{m-inter-row-1}, \code{m-inter-column-2}, \code{m-tiling-cell-1}, \code{m-tiling-row-2}, and \code{m-tiling-column-3}.
+
+\section{Styling}
+\label{sec:styling}
+
+The skeleton nodes are PGF nodes not meant to be styled.
+Styles should be applied to nodes whose shapes depend on the skeleton ones.
+
+\subsection{Macros}
+
+Styling in \code{matrix.skeleton} is done with the~\code{fit} library.
+The following macro creates a \code{fit} node with the specified style:
+\begin{verbatim}
+ \fitandstyle{(m-cell-1-1) (m-cell-2-2)}{draw=red};
+\end{verbatim}
+
+It takes an optional argument to place the node in a \code{pgfonlayer} environment:
+\begin{verbatim}
+ \fitandstyle[background]{(m-cell-1-1) (m-cell-2-2)}{fill=red};
+\end{verbatim}
+
+\subsection{\TikZ \code{matrix} Options}
+
+Common styling options are also provided as \TikZ options.
+These options call~\code{label skeleton} before styling the appropriate nodes.
+They take the following form:
+\begin{verbatim}
+ \matrix (m) [style odd rows = {draw=red}] {...};
+\end{verbatim}
+
+\begin{verbatim}
+ \matrix (m) [style odd tiling rows = {draw=red}] {...};
+\end{verbatim}
+
+\begin{verbatim}
+ \matrix (m) [style grid = {draw}] {...};
+\end{verbatim}
+
+\begin{verbatim}
+ \matrix (m) [style tiling grid = {draw}] {...};
+\end{verbatim}
+
+All of these options have an \code{on layer} variant taking the following form:
+\begin{verbatim}
+ \matrix (m) [style odd rows on layer = {background}{fill=red}] {...};
+\end{verbatim}
+
+\section{Examples}
+
+The following examples illustrate the styling capabilities offered by \code{matrix.skeleton}.
+
+\subsection{Grid}
+

+\section{Internals}
+
+\code{matrix.skeleton} was heavily inspired by \href{http://tex.stackexchange.com/users/86/andrew-stacey}{Andrew Stacey}'s \code{matrixcells} \LaTeX{} package.
+It has three distinctive features.
+First, it works with any \code{anchor}.
+Second, it provides finer control with respect to \code{row sep}, \code{column sep}, and \code{inner sep}.
+Third, the skeleton node positioning relies only on \TeX{} and PGF, not on \LaTeX{} or \TikZ.
+
+\code{matrixcells} properly aligns its \code{cells} when the node \code{anchor} is \code{base}.
+However, when the alignment is different it runs into problems, as exposed in the following \href{http://tex.stackexchange.com}{\TeX{} - \LaTeX{} Stack Exchange} question: \href{http://tex.stackexchange.com/questions/128045/matrixcells-problem-with-the-y-axis-only}{Matrixcells problem with the y-axis only}.
+This shortcoming is the result of some loss of information in \code{pgfmodulematrix.code.tex}.
+A dimension used during the placement of nodes is overwritten.
+Therefore, this information is not available to build the grid.
+In \code{matrixcells}, this lost dimension is reconstructed as the average of two other dimensions.
+This method only gives the right dimension when the nodes are anchored at \code{base}.
+To always get proper alignment, the~\code{pgfmodulematrix.code.tex} macro erasing the dimension was rewritten.
+Following \href{http://tex.stackexchange.com/users/3235/percusse}{\code{@percusse}}'s recommendation this change is transparent to the user and does not require updating PGF/\TikZ.
+
+\code{matrixcells} only provides \code{cells} corresponding the \code{tiling-cells} in \code{matrix.skeleton}.
+This tiling behavior is sometimes desired.
+However, it can result in unexpected behaviors when: using a non-base \code{anchor}, using \code{row sep} or \code{column sep}, or when working on boundary nodes.
