I've got a eeg_data_all(cell,size = 1*35), which contains 35*3 cells maybe. I want to sort these data by the 'subid'. How can I do this?

Each eeg_data_all{P,Q} is to be sorted separately by the subid field of its struct, or all eeg_data_all(:,:) are somehow to be sorted together, considering all of the subid for all of the cells?
Is there are reason why you stored struct in cell instead of using a nonscalar struct array?

I've solved this problem by the function nestedSortStruct
eeg_data_all{1,1} = nestedSortStruct(eeg_data_all{1,1}, 'subid'); %sort by subid
