Michael, it is very simple using "If" sentences in this way f[x_] := If[x < 10, 0, If[x > 20, x/2, x]] ======================================= Juan Egea Garcia Departamento de Matemática Aplicada Universidad de Murcia España +34 968654243 +34 968367144 -----Mensaje original----- De: Michael Popp [mailto:popp.michael at gmx.at] Enviado el: lunes, 27 de mayo de 2002 7:17 Para: mathgroup at smc.vnet.net Asunto: [mg34556] Define a function Hello I want to define a function in Mathematica. But just f[x_]:=... does not work, because I have to define different functions for different ranges of the variable x. For example: x < 10: f(x) = 0 10 < x < 20: f(x) = x 20 < x: f(x) = x/2 How to do this? Thanks, greetings Michael
