Saving the output from a for loop

I am using the following script in MatlabR2015a:

CVO = cvpartition(y2,'k',10);
C=zeros(96,1)
for i = 1:CVO.NumTestSets
  trIdx = CVO.training(i);
  teIdx = CVO.test(i);
  mdl = fitcnb(x1(trIdx, :),y2(trIdx, :),'Distribution', 'kernel')
  [label, Posterior] = predict(mdl,x1(teIdx, :))
  C(teIdx)=Posterior (:,2);   
end
[X,Y,T,AUC] = perfcurve(y2,C,'true','NBoot', 1000); % Curva ROC para os dados de teste do crossval
c1=round(C);
CMat=confusionmat(y1,c1);

How can I save in my workspace the model from each iteration?

Many Thanks,

You can save it as a cell array (note the curly brackets ‘{}’):

mdl{i} = fitcnb(x1(trIdx, :),y2(trIdx, :),'Distribution', 'kernel');

If you want to save the ‘mdl’ cell array after the loop, use the save function to save it to a .mat file. See the documentation for save for details.

Note that it is also recommended to preallocate cell arrays.
