Hello all,
I have a 1 x 3 cell which represents monthly data from 1989 to 2016 for 3 models (each cell arrays is for one model). I want to calculate average value of the precip column of these 3 models for monthly 1989 to 2016. So the output will be a 1 x 1 cell which contains the average value of precip in all models from 1989 to 2016 (monthly). It is so hard for me and I tried some codes but they are not accomplished well.
This is a sample data sets and I have more than 100 cell arrays which some of them ends in 2018 instead of 2016.
Thank you so much.

mnTemp=cellfun(@(t) mean(t.precip),SAMPLE);
with the sample dataset:
>> cellfun(@(t) mean(t.precip),SAMPLE)
ans =
27.8985 62.4198 43.8376
>>
Don't provide any details on how these data/models were created but would be much easier to combine the various data into one table or timetable with the column variables representing the models.
ADDENDUM:
It's still the wrong way to store the data, but...
mnTemp=mean(cell2mat(cellfun(@(t) (t.precip),SAMPLE,'UniformOutput',false)),2);

You can just as easily make a table out of them as not....just keep a corollary variable of the condition.
If you can average across them, then you can certainly combine them in some fashion to be able to do so far more easily than this.
There's not enough information on the specifics to be able to specify what the better storage model would be, but certainly this isn't it.
