In GUI, RangeSlider 's Value may have a wrong type

The offical document says that it is a two-element numeric array, But when I try to get value from it like this:

[minFrq,maxFrq] = app.FilterHzSlider.Value;

it throw a error, said that the number of value is not enough.So I have a test:

X = app. FilterHzSlider.Value;
disp(class(x));

the result is:

double

then I try this:

x=app.FilterHzslider.value;
disp (num2str (x));

then result is:

50 1000

It is confusing.

No confusion. You will find

X = app. FilterHzSlider.Value;

X is returned as [50 1000].

So you would do

minFrq=X(1);

maxFrq=X(2);
