Hi, with my Mathematica 4.0 on a SGI I can't reproduce the bug. In[3]:= (Plus @@ ixr)/Length[ixr] Out[3]= -0.338037 tmp = 1/Sqrt[Length[ixr]] Fourier[ixr] [[1]] Abs[tmp] Out[4]= -0.338037 + 0. \[ImaginaryI] Out[5]= 0.338037 Regards Jens Hans Steffani wrote: > > I placed my data, an a mathematica notebook at > http://www.tu-chemnitz.de/~hfst/mathprob/ > > I tried to build an artificial example which is shorter but > failed. > > Perhaps anyone can help me. > > h.f.s. > -- > Hans Friedrich Steffani > Institut fuer Elektrische Maschinen und Antriebe, TU Chemnitz > mailto:hans.steffani at e-technik.tu-chemnitz.de > http://www.tu-chemnitz.de/~hfst/
