Population Standard Deviation

[Eirik Rosvold Larsen]

Standard deviation can be calculated by two methods:

1) Sample Standard Deviation (implemented by breeze)

2) Population Standard Deviation (default implementation of std in i.e numpy)

https://en.wikipedia.org/wiki/Standard_deviation

I need to port some python code, and thus need the population standard deviation. Is there such a function (UFunc) in Breeze?

If not, do you plan to add it?

Regards, Eirik

there isn't. I don't have any plans to add it, but would accept a PR that added it.
