Undefined function 'nanmean' in MATLAB R2013b

When trying to access the nanmean function in MATLAB R2013b I get the following error:

Undefined function 'nanmean' for input arguments of type 'double'

This happens even when pasting the nanmean example given in the documentation.

Is this function not supported yet in MATLAB R2013b even if it is included in its documentation?

Beatriz, you possibly have not installed/licensed the corresponding toolbox(es). What do you get when you execute in the MATLAB command window

 which nanmean

It should be something like

 C:\Program Files\MATLAB\R2013b\toolbox\stats\stats\nanmean.m

Alternatively you could use

 ver

to get a list of all installed toolboxes and

 license('test','Statistics_Toolbox')

which will return

 ans =
     1

if you have the Statistics Toolbox licensed.

How could she have it in her documentation if it's not installed? (Unless she got it from the online documentation instead of her own local documentation.) I don't have functions in my documentation for toolboxes I don't have installed.
