How to close msgbox after loop finishes?

Hello All, I need help with msgbox() function. I want it to show at the start of my calculation and then after calculation ends, I need it to close automatically,

So basically I have created GUI where after clicking "calculate" pushbutton, the script runs.

So before the calculation starts I have this:

   h=msgbox('Please wait.Calculation in progress...');..

Now I want it to close once the calculation is finished. So after calculations I have added

delete(h);

And I am getting error:

Error using delete
Invalid or deleted object.

I tried with close too but no luck. Please suggest!

It is possible you overwrote h during your calculations and closed it inadvertently.

adi - have you created this GUI using GUIDE or programmatically? Where do you create the message box (which method) and where do you try to close it?

You may want waitbar instead.

If you are using R2014b or later, then use

if isvalid(h); delete(h); end
