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
