% Button pushed function: BUBBLEButton_3
function BUBBLEButton_3Pushed(app, event)
list = num2str(app.INPUTARRAYEditField.Value);
sorted_list = bubble(list);
app.SORTEDARRAYEditField.Value = mat2str(sorted_list);
end

It looks like you are sorting characters, not numbers. Did you mean to use str2double instead of num2str? You can't enter an array in a numeric edit field, so you must be using a text one. That means your values are already strings, so num2str isn't doing anything.

That error is saying there is a problem with your bubble sort function bubble. Specifically, the output variable, bubble_sort, is not being assigned a value.

Sorry, this appears to be one of the rare times you have to use str2num. You'll get a code analyzer warning recommeding str2double. Ignore it. When there is more than one number in the character array, it returns NaN.

If you use num2str instead of mat2str to convert it back, it won't have the brackets around it.
