Averaging in a cell array
조회 수: 1 (최근 30일)
I have a cell array named data (4856x24). The data looks as follows
I want to write a function that averages out the values in each row for positive emotions (Happy,Romantic,Devotional,Calm) and negative emotions(Angry,Longing,Sad,Tensed).The averaged out value column names should be positive and negative respectively. Can anyone pls help. Thanks in advance.

t1 = ~cellfun('isempty',regexp(data(1,:),'Happy|Romantic|Devotional|Calm'));
t2 = ~cellfun('isempty',regexp(data(1,:),'Angry|Longing|Sad|Tensed'));
out = [data(1,:);cell(1,size(data,2))];
out(2,t1) = num2cell(mean(cell2mat(data(2:end,t1))));
out(2,t2) = num2cell(-mean(cell2mat(data(2:end,t2))));

If you convert that to a table (cell2table) and covert the feelings to a categorical, you can then use grpstats and varfun to do this for you, grouping by whatever you want.
If you post the mat file (as a zip) I can help you through these steps, it'll be much simpler and easier to understand than regular expressions/cellfun.
