Dear, I'm training a decision tree for classification with fitctree function and I'm using the oprion

'Surrogate', 1

mdl = fitctree(X,Y, 'Surrogate', 1)

so that at each brach a Surrogate is found in case of missing value.

When the tree is trained, with the view command

view(mdl, 'Mode', 'graph')

I may view the resulting tree.

However, in the tree I see one alternative.

How can I see the surrogate branch???

THANKS!!!!
