Model Explorer (GUI)
Running the Msc classifier with parameter visualize set to true will launch Model Explorer GUI. From it you can browse model structures, visualize their connections, check their errors, list their coefficients, and extract their algebraic form.
Hover the mouse over a node to preview it; errors will appear on the right side and its polynomial formula on the bottom. Click on the node to select it. If multiple nodes are selected, use the Cycle button in the lower right corner to iterate through selected nodes. The zoom slider on the right can be used to adapt view.
