Hi all! I've made the following for loop, where 4 outcomes go into a new matrix in 4 different columns (for target 1, 2, 3 & 4). Now I want these outcomes all added as 1 extra column in matrix 'res', in the right order so that each outcome is paired with the correct trial number. Can somebody please help me with this??

res = S.res;
trials = res(:,1);
targets = res(:,7);
responses = res(:,8);
oria = [3,4,5,6];
tar = [1,2,3,4];
num = numel(oria);
out = cell(1,num);
for k = 1:num
    tarsel = targets==tar(k);
    resp = responses(tarsel);
    orib  = res(tarsel,oria(k));
    err = resp - orib;
    err(err<-90) = err(err<-90)+180;
    err(err>90)  = err(err>90)-180;
    out{k} = err;
end 
out = [out{:}];

As per my understanding of the question, this is a possible solution

res = S.res;
trials = res(:,1);
targets = res(:,7);
responses = res(:,8);
oria = [3,4,5,6];
tar = [1,2,3,4];
num = numel(oria);
out = cell(1,num);
%% Find the number of rows in res
resSize = size(res);
rows = resSize(1);
%% Define a vector containing zeros to map out with corresponding trials
vout = zeros(1,cols);
for k = 1:num
    tarsel = targets==tar(k);
    resp = responses(tarsel);
    orib  = res(tarsel,oria(k));
    err = resp - orib;
    err(err<-90) = err(err<-90)+180;
    err(err>90)  = err(err>90)-180;
    out{k} = err;
    %% store all outputs in corresponding positions
    vout(tarse1) = err;
end 
out = [out{:}];
%% Concatenate vout to the last column of res
res = [res, vout]
