Hi,
Mathematica hangs up when trying to compute the Fourier transform of
F[X_, Y_] :=
E^(-100 + 20*X - 2*X^2 - 10*Y - Y^2/2) +
E^(-100 - 2*X^2 - 10*Y - Y^2/2 + 10*(10 + Y)) +
E^(-200 + 20*X - 2*X^2 - 10*Y - Y^2/2 + 10*(2*X + Y)) +
E^(-200 - 2*X^2 - 10*Y - Y^2/2 + 10*(10 + Y) + 10*(2*X + Y))
FourierTransform[F[X,Y],Y,P]
(keeps running forever)
However, it computes very fast the Fourier transform of each term
separately. I am using Mathematica 4.1 in Windows 2000. Mathematica 2.2
computed correctly this fourier transform.
Any idea?
