I'm trying to split my data in random partition.
I have a code of this type :
cv = cvpartition(size(my_data,1),'HoldOut',0.4);
idx = cv.test;
dataTrain = split(~idx,:);
dataTest = split (idx,:);
The problem is that it provides me dataTrain as a (0x12)table instead of (1200x12)table.
How can I fix this problem ?
