Hello, I am using Mathematica for Students 3.0.1 with Windows 98. When I execute the following code, I get the error messages below: In[1]:= <<Calculus`FourierTransform` In[2]:= Clear[fx, fw, a] In[3]:= a:=1 In[4]:= fx[x_]:=Exp[-Abs[x*a]] In[5]:= fw[w_]:=InverseFourierTransform[fx[x], x, w] In[6]:= Plot[fw[w], {w, -5*a,5*a}] Plot::plnr : fw[w] is not a machine-size real number at w = -5.. Plot::plnr : fw[w] is not a machine-size real number at w = -4.59433.. Plot::plnr : fw[w] is not a machine-size real number at w = -4.15191.. General:: stop : Further output of Plot::plnr will be suppressed during this calculation. Does anyone know where I might obtain a corrected FourierTransform.m package for Mathematica 3.0.1? My copy is dated 7/21/97. I contacted Wolfram about this matter. However, they told me they no longer support version 3.0. I appreciate any help you may provide. Thanks. David
