% Button pushed function: FINDINDEXButton

function FINDINDEXButtonPushed(app, event)

list = str2num(app.INPUTARRAYEditField_2.Value); % get input array

sorted_list = num2str(quick_sort(list,1,numel(list)));

value = str2num(app.INPUTFORSMALLESTELEMENTINTHEARRAYEditField.Value);

result = sorted_list(value);

app.RESULTEditField.Value = result;

end

When I search for 2 then it must be 23, but now it has seen 1.

What are you trying to accomplish?

Sorted list is a string array containing a single element. You appear to be trying to index it like it is a numeric vector. Don't convert it to a string until you are ready to write it back to the edit field.

I want to find i'th smallest element in the array.
