individual objects differently, however, it is also possible to
change the overall spacing of a matrix by inserting the
following codes <em>between</em> <code>\xymatrix</code> and the following <code>{</code>:<P><CENTER><TABLE BORDER=BASIC CELLPADDING=3 COLS=2><TR><TD> <code>@=</code><em>dimen</em> <TD> set spacing <TR><TD>
<code>@R=</code><em>dimen</em> <TD> set row spacing <TR><TD>
<code>@C=</code><em>dimen</em> <TD> set column spacing <TR><TD>
<code>@M=</code><em>dimen</em> <TD> set entry default margin <TR><TD>
<code>@W=</code><em>dimen</em> <TD> set entry default width <TR><TD>
<code>@H=</code><em>dimen</em> <TD> set entry default height <TR><TD>
<code>@L=</code><em>dimen</em> <TD> set label margin
</TABLE></CENTER><P>
<P>
<code>=</code> can be replaced by any of <code>+</code>, <code>+=</code>, <code>-</code>,
and <code>-=</code> of section <A HREF="node13.html#arrowsobjects">2.2</A> with the same meaning,
<I>i.e.</I>, replace "set" with "increase," "increase to at most,"
"decrease," and "decrease to at least," respectively. For example,
<code>$\xymatrix@1@=0pt@M=0pt{A&B\\C&D}$</code> in the text typesets <IMG WIDTH=31 HEIGHT=36 ALIGN=BOTTOM ALT="tex2html_wrap2750" SRC="img64.gif">.
<P>
In case <em>uniform spacing</em> is desired, several alternative
forms exist.
<P><CENTER><TABLE BORDER=BASIC CELLPADDING=3 COLS=2><TR><TD> <code>@!</code> <TD> force all spaces equal <TR><TD>
<code>@!0</code> <TD> -- and ignore entry sizes <TR><TD>
<code>@!R</code> <TD> force equal row spacing <TR><TD>
<code>@!C</code> <TD> force equal column spacing
</TABLE></CENTER><P>
<P>
Finally a special notation allows <em>rotation</em> of an
entire matrix:
<P><CENTER><TABLE BORDER=BASIC CELLPADDING=3 COLS=2><TR><TD> <code>@</code><I>d</I> <TD> rotate towards <I>d</I>
</TABLE></CENTER><P>
<P>
Only the matrix grid will rotate, however, not the actual contents.
