Save Regression Tree using Matlab commands

Hi,

I generated a regression tree using RegressionTree.fit() command and I was able to view/save the tree using GUI as a result of command view(treename,'mode','graph'). However, I was not able to complete the saveas() procedure using Matlab commands, as I found no way to access the figure generated by the view() command.

I browsed some previous post including:

http://www.mathworks.com/matlabcentral/answers/68349-how-to-save-decision-tree-view-classification-tree-viewer

which suggests that I can assign a handle to the figure, for example :

h = view(treename,'mode','graph')
saveas(h,'filename','format')

However, when I attempt to do so with my Matlab R2013a, the command I mentioned above generated an error message:

>> h = view(treename,'view','graph')
Error using RegressionTree/view
Too many output arguments.

Can someone please offer some instructions on this?

Thanks in advance!

You can choose SaveAs from the figure pop-up menu when you click on File in the upper left corner.

If you can't find SaveAs for some reason, try this:

prunelevel = 0;
h = treename.Impl.viewGraph([],treename.NodeMean,treename.PredictorNames,prunelevel,'')
