How to get lower and upper bounds for portfolio optimization in Gui?

LowerBound = [app.EditField.ValueChangedFcn;app.EditField2.ValueChangedFcn;app.EditField3.ValueChangedFcn];

UpperBound= [0.5; 0.5; 0.5] I want to get bounds like this but ı am receiving error. (Nonscalar arrays of function handles are not allowed; use cell arrays instead.

P = setBounds(P, LowerBound, UpperBound)

% Value changed function: EditField

function EditFieldValueChanged(app, event)

value= app.EditField.Value;

app.LowerBound=value;

I have 3 edit fields like this. For 3 asset 3 weights.
