While I'm thinking about it, here are a couple more things from LaTeX's math stuff that might be useful to include in m-newmat: The \stackrel command is listed as "a disguise for plain TeX's \buildrel", much like \frac is a "disguise" for \over: \def\stackrel#1#2{\mathrel{\mathop{#2}\limits^{#1}}} There's also the \lefteqn command: \def\lefteqn#1{\rlap{$\displaystyle #1$}} The \lefteqn command is useful for doing partly-aligned equations, of the sort that get displayed as: long left-hand-side = long right-hand-side part 1 + long right-hand-side part 2 + long right-hand-side part 3 Essentially, you'd write that in an eqalign (or something like it), as: \placeformula \startformula \eqalign{% \lefteqn{long left-hand-side}\qquad & \cr &= long right-hand-side part 1 \cr &\quad {}+ long right-hand-side part 2 \cr &\quad {}+ long right-hand-side part 3 \cr } \stopformula As can be seen, \lefteqn lets the long left-hand-side overlap the alignment point, without shifting it excessively to the right. It's not perfect -- for one thing, if the left-hand-side extends farther to the right than the right-hand-sides, the equation won't be centered -- but it's a good start and works right most of the time. :) - Brooks
