iagonals around the main diagonal, including the main diagonal itself: <code>[-1,0,1]</code>.
If <code>theiler</code> is a numeric vector of <code>length(theiler) == 2</code> it is possible to exclude an asymmetrical window. The values are interpreted as end points in a sequence of diagonal ID's, e.g. <code>theiler = c(-1,5)</code> will exclude <code>[-1,0,1,2,3,4,5]</code>. If <code>length(theiler) &gt; 2</code>, the values will be considered individual diagonal ID's, e.g. <code>theiler = c(-3,-1,0,2,5)</c
