NeXT Computer OS 2.1 Mathematica V2.1 Dear MathGroup, Does anybody know why the integration routines are failing here?: X[z_] := 1/(1 - a z^-1) Needs["Calculus`DiracDelta`"] a=0.5; ContourIntegral = Integrate[X[E^(I w)] E^(I w n), {w, -Pi, Pi}] / (2 Pi) (* no answer given *) I n w E Integrate[-------------, {w, -Pi, Pi}] -I w 1 - 0.5 E -------------------------------------- 2 Pi Jon Dattorro, Ensoniq Corp. jond at Ensoniq.com
