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);
