Clearly, you passed too many inputs to nanmean. Crucially you haven't shown us how you call nanmean so it's difficult to say exactly what you do wrong.
Note that since R2014b (I think), there is no need to use nanmean, the regular mean function can ignore nans.

You may have your own function or a variable that you named ‘nanmean’.
Run this from a script or your Command Window:
which nanmean -all
If the first result is:
nanmean is a variable.
You have found the problem. The solution is to re-name your function or variable to something that does not overshadow any MATLAB functions, and is meaningful to you.

If your using 2018b version just use mean with 'omitnan' as a name pair
doc mean % if and only if your using 2018b to use them with n dimensions
