Help with my code

Hi i keep getting this error but i am not sure what it means, can anyone help?

Unrecognized method, property, or field 'train' for class 'cvpartition'.

Error in Ma (line 27)

BCTabletrain = cvfolds.train(i);

cv = cvpartition(n,'kfold', k);
cp = classperf (OutputVariable);
  for i = 1:k
   test = cv.test(i); 
   TrainSet = cv.train(i);

Why did you write that? Why do you think a cvpartition object has a "train" property, method, or field?

i am not very experienced with matlab so i was following someone's example i thought it was the number of elements in (each) training subset., so does that mean if i am trying to do a k fold cross validation i do not need it.

TrainSet = cv.training(i);
