Unable to use the nanmean function

I just updated my matlab to 2015b but I can't find the nanmean function in it. When I write help nanmean it says nanmean not found. Is there a separate toolbox for that function, and if so which one? Thanks!

Use [name of internet search engine] to locate the documentation:

http://www.mathworks.com/help/stats/nanmean.html

In the address the word "stats" means the Statistics Toolbox, so you know the toolbox without even opening the page. Also when you open that page the Contents on the left hand side look like this:

> All Products
> Statistics and Machine Learning Toolbox
> Descriptive Statistics and Visualization
> Descriptive Statistics

which also tell us that this function is in the Statistics toolbox.

Since you're using release R2015b, instead of using NANMEAN from Statistics Toolbox you can use MEAN from MATLAB with the 'omitnan' flag.

nanmean is part of the Statistics toolbox.
