\section{Vectors}

A vector is a matrix with one column:

\[
\begin{array}{l}
a \\ 
b
\end{array}
\]

or one row:

\[
\begin{array}{ll}
c & d
\end{array}
\]

You can toggle on and off the outline of the vector cells with the Matrix
Lines command on the \hyperref{View menu}{}{}{View_menu_commands.tex}. The
outlines do not print.

\subsubsection{$\blacktriangleright $\quad To enter a vector with commands}

\begin{enumerate}
\item  Click\FRAME{itbpF}{22.4375pt}{21.0625pt}{2pt}{}{}{matrix.wmf}{\special%
{language "Scientific Word";type "GRAPHIC";maintain-aspect-ratio
TRUE;display "PICT";valid_file "F";width 22.4375pt;height 21.0625pt;depth

"1";cropright "1";cropbottom "0";filename 'Matrix.wmf';file-properties
"XNPEU";}}, or from the Insert menu, choose Matrix.

\item  Use the Matrix dialog box to set the dimensions and the vertical
alignment of the vector, and the \hyperref{alignment of the columns}{}{}{%
Align_matrix_columns.tex} within the vector.

\item  Choose OK.

The program places the insertion point in the first \hyperref{cell}{}{}{%
Glossary.tex#cell} of the vector.

\item  Type the first value in the vector.

\item  Press Tab to move to the next cell.

\item  Press the spacebar or the right arrow to leave the vector.
\end{enumerate}

\subsubsection{$\blacktriangleright $\quad To insert a column vector with
the keyboard}

\begin{enumerate}
\item  Type the first value in the vector.

\item  Press Enter.

The program displays an \hyperref{input box}{}{}{Glossary.tex#input box}
under the first value.

\item  Type the next value in the input box.

\item  If you need to enter another value, press Enter.

\item  Continue until the vector is complete.

\item  Press the spacebar or the right arrow to leave the vector.
\end{enumerate}

\subsubsection{$\blacktriangleright $\quad To enclose a vector in brackets}

\begin{enumerate}
\item  Select the matrix.

\item  Enter the brackets.\medskip 
\end{enumerate}
