Hi guys I have tried to conduct a two sample t test on two matrix x and y where x is a 175x16 matrix and y is 1x16 matrix but the matlab gives me the following error:
h=ttest2 (x,y)
Error using mean
Too many output arguments.
Error in nanmean (line 17)
y = mean(varargin{:},'omitnan');
Error in ttest2 (line 171)
difference = nanmean(x,dim) - nanmean(y,dim);
Does anyone know a soultion for this?
Thanks for the help in advance.

Somewhere in your code there is a custom function named "mean" (or it could be a global variable). You have to find where that happens and rename it to something else.
I'd start by searching for
which mean -all
which will likely list several function on your path, many of which will be followed by "Shadowed...". You'll need to look for any custom function in that list.
A temporary solution would be to clear "mean" just prior to calling ttest2() but this doesn't address the root of the problem.
clear('mean')
ttest2(....)
