How to position a GUI centered on the desktop

I am trying to center my GUI on the desktop but I am not sure where in the code I put the command

I am using

movegui('center') and movegui(IAM,'center')

Not sure if both would work the same but where in my code does the command go so when every time I open it, it will be positioned center on the screen.

Where to put it exactly depends whether you are using a GUIDE GUI or a programmatic one.

I forgot the function exists so I position my UIs manually, but the examples seem to suggest you just put it straight after you create the figure. And if you want you can create the figure off-screen initially so that you don't get a jumping effect of it moving from one on-screen location to another.

In a GUIDE GUI I would think the OutputFcn should work as a place to put it. I'm not sure about the OpeningFcn since the figure doesn't exist until that function has completed.

I am using GUIDE and it works perfectly under both options. Thank You

When I run the code that opens it, it will recognize it. Also when I call that GUI from another GUI it recognizes it

Only issue now it when I open just the figure from the folder directory it doesn't recognize a centered position. Its not the worst thing but still would like to solve that if you have any ideas

As far as I am aware opening the figure from the folder directory will literally just load it as if it were a saved figure. It will have no functionality underneath it and hence will not call the OpeningFcn when it opens. I'm not sure what usefulness opening it this way has though.
