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!

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?

If you are using R2014b or later, then use
if isvalid(h); delete(h); end
