Hi Daniel, I've been using the Fourier transform command to obtain a frequency domain expression of my function, then taken its absolute value by multiplying by the complex conjugate, then plotted the result. It's all just standard stuff, so I guess I thought there would be a sort of signal-processing toolbox to do this, and other related things. I'm just exploring.
By the way, why is that the following command gives me a result (FT of a Dawson function):
Fourier transform of Dawson(sqrt(t)*theta(t))
but the following (same thing, but with time multiplied by a constant:
Fourier transform of Dawson(sqrt(at)theta(t))
does not? This difference is just an example of how sometimes Wolframalpha works well, but at other times, for reasons I don't understand, it doesn't.
Thank you,
Jeff
