MATLAB: Waitbar jumps to center screen on update

MATLABwaitbar

Is there a way to prevent the waitbar from jumping back to the middle of the screen upon update?

I'd like to have another waitbar on my screen. i'd just move one waitbar to the side in the beginning of my calculations.

Updating the waitbar does not change the position of the window. So if you observe a changed position, your code must contain the explicit instruction to do so. Perhaps you create a new waitbar in each iteration instead of updating the value only. If you post some code, which reproduces the observed behavior, we can find the problem.

Such cases are handled using persistent variables.

function [ia_avr] = fcn(ia)
    persistent iasum ia_num ia_avr_old
    
    if isempty(iasum) % only runs once
        iasum = 0;
        ia_num = 0;
        ia_avr_old = 0;
    end
    
    iasum = iasum+Ia; 
    if xxxx
        ia_num=ia_num+1;
        ia_avr=ia_avr_old;
    elseif xxxx
        ia_num=ia_num+1;
        ia_avr=iasum/ia_num;
        ia_avr_old=ia_avr;
    else            
        ia_avr=ia_avr_old;
        iasum=0;
        ia_num=0;
    end
end

MATLAB: How to close waitbar

If you have a waitbar that you are finished with, close() its handle. The handle can be returned when you first create the waitbar:

h = waitbar(x,'message');

then you would close(h) when you are done with it.
