Hi everyone,

In appDesigner, I imported data for statistical analysis, through a matrix of (observations x variables).

I generated a uicheckboxtree from the variables names, and would like to be able to check the nodes of relevant variables to then process to statistical analysis.

I cannot find the way to extract usable information from the figure object 'CheckBoxTree' ...

I was hoping to get some sort of a 0 | 1 | 1 | 0 test for the selected/unselected nodes, from which I could filter relevant data.

Or maybe there's another more relevant way to achieve what I'm trying to do (destined to simplify and automate processes for non-MatLab users ?).

Thanks in advance for your help !

在 MATLAB Online 中打开

Well I found a way, maybe not the best one but it works so far for what I needed to do, so, if it can help anyone...

            for i = 1:1:numel(app.tree.CheckedNodes)
                app.sDATA(:,i) = app.DATA{:,(app.tree.CheckedNodes(i).Text)};
            end
            

where DATA is a table where the VariableNames are identical to the tree nodes text labels.
