How do I use the "omitnan' option for the Mean function when calling the function using the splitapply function?
显示 更早的评论
I would like to use the following command: splitapply(@mean,MyArray,G) but call the @mean function using the "omitnan" option. How can I do that? In this example, MyArray is the array that I would like to apply the mean function to after I have split it into Groups dictated by the G vector

One option:
splitapply(@(x)mean(x,'omitnan'),MyArray,G)

How would I use 'omitnan' in this scenario?
varfun(@mean,timetable,'GroupingVariable','Date & Time');

Probably:
varfun(@(x)mean(x,'omitnan'),timetable,'GroupingVariable','Date & Time');
That should work, although since I didn’t test it, I’m posting it as UNTESTED CODE. (I never tried that with varfun, however I have tried it in similar situations.)
If you have the Statistics and Machine Learning Toolbox, you can use nanmean with only the function handle and not the full anonymous function construction.
