Issue with Dim argument in TTest2 and ANOVA1

[boergertf]

When trying to use several of the tests (e.g. ttest2, anova1) I ran into an issue with the call for "sum" and "mean". For example, when running permuanova1 I received the error:
"Error using sum
Invalid option. Option must be 'double', 'native', 'default', 'omitnan', or 'includenan'.

Error in permuanova1 (line 95)
nobs = sum(~isnan(x), 'all'); " It appears to me that the issue is with argument 'all' . When I tried deleting 'all', it through the same error for 'mean' in line 98.

I'm running it on MATLB 2018a on a computing cluster.

permucorr worked great on the other hand.

Is this likely to be a matlab version issue?

Thanks

Hi Timothy,

Thanks for bringing this issue to my attention. Unfortunately I believe it is a MATLAB version issue. If you do not have access to a more recent version of MATLAB, you can always replace sum(x, 'all') with sum(x(:)). I will try to find a solution to this in the meantime.

What was the specific error you were receiving with permuttest2?

Cheers,
Mick
