Hello.
When i execute this code:
treetraining = fitctree(X(d.training,:),classNames(y(d.training,:)+1),'SplitCriterion','gdi','PredictorNames',attributeNames,'Prune','off','MergeLeaves','off','MinParent',100)
There is nothing wrong and I get a nice tree. When I execute this code after (or any argument in prune):
tree2 = prune(treetraining);
I get an error:
Error using subsindex
Function 'subsindex' is not defined for values of class 'ClassificationTree'.
I am doing the same thing the help page of prune did in the example. What am I doing wrong?
