MATLAB: Close classregtree window programmatically

classregtreeStatistics and Machine Learning Toolboxview(t)

If I use the Statistics Toolbox tool classregtree like this:

load fisheriris; t = classregtree(meas,species,… 'names',{'SL' 'SW' 'PL' 'PW'}) view(t)

….the classification tree window pops up as expected.

How can I close this window from the command line? I cannot find the handle of this object to close it.

Any help appreciated.

I believe it creates a figure whose handle visibility is off. I do not know the name of the figure. Try

hiddenfigs = findall(0,'Type','figure', '-not', 'HandleVisibility', 'on');

It is possible to save the tree picture by using the handle of the Figure that shows the tree. First you need to ask for the handle with the VIEW method:

h = view(t);

Then you can use any of the save or print functions that work on a figure handle, for instance:

saveas(h, 'myTree.png')
