[comp.text] Double subscripts in LATEX summations

phs@lifia.imag.fr (Philippe Schnoebelen) (07/10/89)

What are the cleanest LATEX instructions to obtain double subscripts in an
indexed summation, as in:

			   ------
		           \
			    >	     a[n,m]
			   /
			   ------
			 n=1,...,10
			 m=1,...,10


Answer by mail if possible. Much thanks in advance.

this may be of general interest. I don't know why I couldn't use \ldots
directly - it kept complaining that I should have been in mathmode.

\def\ld{\copy\ldbox}

$$
\sum_{\vtop{\hbox{n=1,\ld,10}\hbox{m=1,\ld,10}}} a[n,m]
$$
