datas6=data(:,indA6(1:d));
data6=[datas6 data(:,m)];
%%data6 classify%%tanimoto
[n,m]=size(data6);
for k=1:it
test=data6(test_rows,:);
train=data6(train_rows,:);
xtest=test(:,1:m-1);
ytest=test(:,m);
xtrain=train(:,1:m-1);
ytrain=train(:,m);
[rforest, DT , sk ] = classificationa(xtest,xtrain,ytrain);
[Arforest6(k), ADT6(k) , Ask6(k)] = allaccuracydata(rforest, DT , sk , ytest);
end
averf6=mean(Arforest6);
avedt6=mean(ADT6);
avesk6=mean(Ask6);
x6=[averf6, avedt6 , avesk6];
disp('tanimoto'); disp(x6);
In this code d is the number of selected features(columns) so we use 10 features of the data(colon attached) to classify It, my question is suppose that we want to obtain the average of Arforest (averf6) once for d=10, once for d=20,for d=30,d=40 and d=50 and save the results of averf6 for each of them in one array(forexample a) to plot the array.
how can I save the results of these different runing the program, in one array based on changing in d [10 20 30 40 50], I have problem in this part, and also how to define d that have several values, should I define d as an array forexample d=[10,20,30,40,50]; ?
Thanks

Assuming that those means are scalar values, then a simple loop:
dV = [10,20,30,40,50];
nV = numel(dV);
averf6 = nan(1,nV);
avedt6 = nan(1,nV);
avesk6 = nan(1,nV);
for jj = 1:nV
d = dV(jj);
... your code
averf6(jj) = mean(...)
avedt6(jj) = mean(...)
avesk6(jj) = mean(...)
end

"...sure I use ctrl+i to indent the codes.I hope that the structue will be better."
Your code has exactly the same indentation as before. I cannot follow it.
Please align your code consistently in the MATLAB editor
- select all of the code
- press ctrl + i

"should I use these lines in the for k=1:it loop?"
Yes. That is exactly what I showed you. Then you can check what results are generated on each loop iteration, and continue to investigate the iterations that are not generating the results that you expect.
