How can I define something like the following(which does not work as written): b[t_/;(x[k_]<=t<x[k_+1])]:=s[k,t] I wish to have this mean the following: b[t_]:=Which[x[1]<=t<x[2],s[1,t],x[2]<=t<x[3],s[2,t],....etc....] where x[k_]:=numbers[[k]], and numbers is an increasing sequence of numbers, s[k_,t_] are functions of t indexed with k, defined for t in the interval {x[k],x[k+1]}. Any help on this would be appreciated. Jay H. Wolkowisky Dept. of Math. University of Colorado, Boulder wolkowis@euclid.colorado.edu
