How can delete a msgbox in a function

Dear All,

I have a function that have at the end a msgbox. When i call
this function in one way i want to show this msgbox, but if
i call function in another way i don't want to show it. How
i can call the function without show msgbox?

Thanks

Francesco

Sorry, I am not clear on what you mean by calling the function
"in another way".

If there is a way that you can determine by examining the input
arguments that the function was called one way or the other, then
you just wrap the msgbox() call within an if/end pair that does
the appropriate test.

Hi Walter,

thanks for your reply. In total i call function 2 times. One
time i want show msgbox, the second one i call same function
but this time i don't want msgbox. Let me know if there is a
simple way to do it.

Thanks

Francesco

one of the many solutions is outlined below
- copy/paste the snippet into a file <foo.m>
- at the command prompt, repeatedly type foo, eg,
     foo % <- shows msg
     foo % <- does not show msg
     foo % <- shows msg

function foo
if ~isempty(getappdata(0,'hasbox'))
     setappdata(0,'hasbox',[]);
else
     msgbox('text','string');
     setappdata(0,'hasbox',true);
end
