Converting and Instrument Object Array (instrfind) into strings?

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

Note that as of R2019b, instrfind is not recommended, you should be using serialport instead.

There is no built-in function that directly convers an instrument object array into strings but it's trivial to write one that simply insert into strings whichever properties of the object you want to display. Therefore, what text do you want displayed?

Hi, thanks for this. So it would just be the coms port and its CURRENT status:

   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

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));
