Undefined function 'nansum' for input arguments of type 'single'.

Are you using a version of MATLAB anterior to 2006a? Evaluate ver or version to check. Or maybe you shadowed the function by naming a variable nansum by mistake during your tests. To check, evaluate
which nansum
and see if you get something like
C:\Program Files\MATLAB\R2015b\toolbox\stats\stats\nansum.m

Marco, since you're using release R2015a (according to your comment on Cedric's answer) you can use SUM with the appropriate nanflag input argument instead of NANSUM.
x = [1:10 NaN];
sum(x, 'omitnan')

Not only does SUM accept this flag, but so do a number of the other basic statistical calculation functions. For a full list, see the second item in the Mathematics section of the release R2015a Release Notes for MATLAB.
