MATLAB: Converting and Instrument Object Array (instrfind) into strings

Question

Hello, Im using an edit box (GUIDE) as a message reported by utilising multi lines (by setting max property >1)

I have a function that I have created to report out important information.

I am using it for RS232 connections, and want to show in my edit box the results of instrfind:

   Instrument Object Array
   Index:    Type:     Status:   Name:  
   1         serial    closed    Serial-COM3
   2         serial    closed    Serial-COM3
   3         serial    closed    Serial-COM3
   4         serial    closed    Serial-COM3
   5         serial    open      Serial-COM3

Here is my ReportMessage function:

function ReportMessage(handles,msg)
 currString=get(handles.editMessage,'String');
 currString=[{msg};currString];  %add to top of message box
 set(handles.editMessage,'String',currString);
 drawnow;

How can I convert and Instrument Object Array into strings?How can I convert and Instrument Object Array into strings?

In particular, I just want to report out any open comms ports

Thanks

I don't have any serial port on this machine so can't really test for the actual property names, but it should be something like:

ports = instrfind('Type', 'serial');
descriptions = compose('%s on port %s is currently %s', string(ports.Name), string(ports.Port), string(ports.Status));
