Plot::plnr: O is not a machine-size real number at x = -1.. General::"stop": "Further output of Plot :: plnr will be suppressed during this calculation.
下の様に書いたんですが、どこが間違ってるんでしょうか?
W = 2 * x I = Exp[x] O = FourierTransform[I, t, ω, FourierParameters -> {-1, 1}] * FourierTransform[W, t, ω, FourierParameters -> {-1, 1}] Plot[O, {x, -1, 1}]
