simpler example for randn #52252
Conversation
As noted by https://discourse.julialang.org/t/how-do-we-julians-win-big-when-the-situation-is-so-unfair/106433/63?u=lmiq the example provided is too complex and does not directly indicate the most typical usage of the `randn` function.
Add simpler example to `randn` function.

I merged in a few more of my changes, hope you don't mind. (I also noticed that the docs were out of date on the supported types due to #44714) |

Possibly you want to mention this is the "standard complex normal distribution", which I believe it is, i.e. same as from MATLAB: https://www.mathworks.com/help/matlab/ref/randn.html#mw_6dadd167-e8bc-42bb-9aaa-9bcfb97f6815 I was expecting circularly symmetric (see that on stack overflow on a question for uniform, and also a square suggested, to show there isn't any one right, as opposed for randn I think). Note, in MATLAB docs there's still an alternative to that "standard" complex randn (it also show e.g. for how to generate Bivariate Normal Random Numbers). I.e. non-standard I would think. Is there a similar way to use randn? All this got me thinking what are possible extensions to e.g. quaternions. https://stackoverflow.com/questions/31600717/how-to-generate-a-random-quaternion-quickly I'm not saying the docs should say anything on this, since Base doesn't have higher-complex, and such docs belong in relevant packages. kieranwynn.github.io/pyquaternion/ Python doesn't have randn I think but numpy does, but it doesn't have for complex it seems, I see a closed and open issue: |
