TeX's \halign is an unusually flexible construct, but it's tough to become proficient in its use (I'm not. I much prefer the macros provided by AMSTeX). Before you start thinking I am a TeX guru (I'm not), I need to say that I stole the following idea from Donald Knuth's "The TeXbook", page 334, example 22.9. The TeXbook ranks as one of the best books that I own. $$ \openup1\jot \tabskip=0pt plus1fil \halign to\displaywidth{\tabskip=0pt $\hfil#$&${}#\hfil$\tabskip=0pt plus1fil & \tabskip=0pt$\hfil#$ & ${}#\hfil$ \tabskip=0pt plus1fil &\llap{#}\tabskip=0pt\cr \omega_1 & =\omega_0=\omega_{\rm s} & Z_1&=\pmatrix{1\cr1\cr}={\bf Z}_{\rm s} & (a) \cr \omega_2 & =-\omega_0=-\omega_{\rm s} & Z_1&=\pmatrix{1\cr1\cr}={\bf Z}_{\rm s} & (b) \cr \omega_3 & =\omega_0\sqrt{1+2f}=\omega_{\rm a} & Z_1&=\pmatrix{1\cr-1\cr}={\bf Z}_{\rm a} & (c) \cr \omega_4 & =-\omega_0\sqrt{1+2f}=-\omega_{\rm a} & Z_1&=\pmatrix{1\cr-1\cr}={\bf Z}_{\rm a} & (d) \cr} $$ David Arnold College of the Redwoods Mathematics Department 7351 Tompkins Hill Road Eureka, CA 95501 (707) 476-4222 My Home Page http://online.redwoods.cc.ca.us/instruct/darnold/index.htm Ordinary Differential Equations Using Matlab http://www.prenhall.com/books/esm_0130113816.html
