How to implement A X B Cross-validation and get the confusion matrix. For example, 5 times 2-fold Cross-validation.

I used this code to implement k-fold only

mdl = fitcknn(inputs,targets);

partModel = crossval(mdl, 'KFold', 5); % 5-fold cross validation

Accuracy = 1 - kfoldLoss(partModel, 'LossFun', 'ClassifError');

[validationPredictions, ~] = kfoldPredict(partModel);

Conf_Mat=confusionmat(targets',validationPredictions);
