Limits cannot be assigned equal.
I would first check the value of 'max (cruiseList)', if it is lower or equal to 1 I would not assign the limits to the spinner. In this case, I would hide it or disable it since it would have no use.
Hiding:
if max(cruiseList)<=1
app.A.Visible = 'off'
app.A.Value = 1;
else
app.A.Limits = [1, max(cruiseList)];
end
Disabling
if max(cruiseList)<=1
app.A.Enable = 'off'
app.A.Value = 1;
else
app.A.Limits = [1, max(cruiseList)];
end
