Statistics from a writetable

I have a code with a for loop that depends on the number of image files in a folder. I could run the loop 4 times if I am processing 4 images or 100 times if I am processing 100 images. Then I create a table with writetable. How can I do statistics (mean and standard deviation) at the end of the write table for each column of data. For example, in column 2 the results are distances. My main issue is the number of data points to average can vary everytime I run the code. Sometimes I need to average B2:B10, it could be B2 through B20...etc.

Thanks,

Hi I am assuming you are trying to use statistics(for eg. mean) for variable size arrays. Try using the "end" to denote the end of the array.

mean(T.Var1(1:end)) % T is the table and Var1 would be the array.
