hi Hazel
read the help for command training
c = cvpartition(10,'kfold',3)
c =
K-fold cross validation partition
N: 10
NumTestSets: 3
TrainSize: 7 6 7
TestSize: 3 4 3
training(c,1)
ans =
0
0
1
1
1
1
1

0

as you can see, the input is not just an array of numbers, it has to belong to a certain class in this case, class cvpartition
checking the class cvpartition we get these different ways that cvpartition objects can be generated:
please, if you find my answer useful, would you be so kind to mark it as accepted answer?
thanks in advance. Regards

If your data are currently in a cell array, consider using the cell2mat function.
If your data are currently in a table, getting the data into a numeric array is a bit more involved. See Access Data in a Table for details.
