This technique might work, but the idea is basically store an index associated with each tab in the tab's UserData (when its created) and then grab that from the event info when the user selects a tab. Then use that index to grab the right tab to get into the data stored on that tab. This method does not require strcmp to find the right tab. Note the first tab's callback is specified in the startupFcn.
Final results: TBD
