I think that we need to improve the integrator capability, but usually that
is one of the most difficult thing to do.
For Fourier transformation to give general functional results (DiracDelta)
than improperly integrable functions, I'm not sure meijerint is sufficient
for that.
But if that is pos
Ah yes, thanks for this. Will the Sympy include these symbolic fourier
transform results?
The last two: -1/t^2 and 2/t^3 can be solved using the time differentiation
and the 'duality' property of Fourier transform. In matlab this can be done
by
syms t w
fourier(-1/t^2)
I used Maple but it doe

Ouch ! Language has failed me. Apologi
A function f on the real line is said to be integrable if the improper
integral of its absolute value from -oo to oo is finite. It does not mean
that it has an antiderivative.
Note also that the piecewise result above is undefined for real values of w
so it does not give a Fourier transform.

Thanks Kalevi!
When will Sympy get updated and be able to compute fourier transform of
difficult functions? I tried this in matlab and it can do it no prob using
the symbolic toolbox.

Fourier transform is currently implemented in SymPy only for integrable
functions. None of those functions is integrable so SymPy cannot be used
find the transform.
