The latter feels more intuitive to me for using an object's method, but I don't know what normal is in Matlab for this. To learn more, see our tips on writing great answers. I am working on a GUI which analyzes data using quite lengthy calculations. Which finite projective planes can have a symmetric incidence matrix? Is it possible to use a waitbar to monitor the progress of a process that spans several functions? The strangest thing is that I don't get this error (or this problem) when using the waitbar in a 'for' loop elsewhere in my program even with more complicated messages such as 'Analyzing data, please wait'. ), Hm, I've been meaning to tidy up my work-in-progress, for quite a while.

Define the helper function updateWaitbar. functions available for creating dialog boxes in figure-based apps and From within your code, you can set the size of a patch object (patch properties) that continually grows as you update its size and then vanishes after reaching 100%. h = waitbar (x,'title') creates and displays a waitbar of fractional length x. But that's far less of a problem than the use of globals with fixed names. The code to do the update calls a private uiwaitbar.p (so I don't know when that might fail), and then if the string is provided tries to set() the String property of the title. Or, you need an estimate about how long your script will be running. Matlabmatlab Is there any reason to do increment(pw) instead of pw.increment? offers.

That one messes up your whole program. Choose a web site to get translated content where available and see local events and offers. Here's roughly what it would look like. Set the number of iterations for your for-loop, N. Store the current number of completed iterations, 0, and the total number of iterations, N, in the UserData property of the wait bar. Example waitbar is typically used inside a for loop that performs a lengthy computation. A waitbar is a figure. Other MathWorks country sites are not optimized for visits from your location. Also, these dialog boxes are displayed within the UI figure window that makes MathWorks. Now that the DataQueue system exists, it should be possible to do this more sensibly. However, no matter what values I assign to percentageDone variable the waitbar in the GUI does not change at all. The code below works nicely, but it depends on using three globals - which isn't great, because if those variable names are being used by something else, it's gonna break stuff. Choose a web site to get translated content where available and see local events and Usage is explained in the first one: %FNPARWAITBAR Produces a waitbar object that works with parfor. 2.
