So I was doing a Fourier transform on a Gaussian distribution, the histogram of which is as follows. And by the way I sampled a million data, as shown in the image.
What is such distribution?
I find Weibull Distribution and Beta Distribution similar to the histogram, but I'm not sure.

The Fourier Transform of a Gaussian should be another Gaussian. Are you sure your code is correct? The histogram you show there is skewed, which I would not expect in a Gaussian. – Adrian Keister Feb 05 '19 at 14:40

You're taking the absolute value in there, right? Is that what you want to do? It's no longer a Gaussian at that point. – Adrian Keister Feb 05 '19 at 14:41

Indeed, I intentionally took the absolute value, as I don’t suppose it is poossible to draw a histogram of complex data – Jonathan Cui Feb 06 '19 at 16:48

What I was wondering was that what this distribution is. – Jonathan Cui Feb 06 '19 at 16:49

The magnitude of the signal follows a Rice distribution: https://en.wikipedia.org/wiki/Rice_distribution
