Hello I didnt found out how to get the value of the Slider to the EditField, and the other way around. Can somebody help me? I am using MATLAB2020b and the App designer, so I don´t have one of these so called "handles" anymore and they are used in every tutorial. thank you

I don't use app Designer, but isn't it something like

value = app.sliderName.Value;
app.EditField.String = sprintf('%.3f', value);

Hello,

first of all thank you very much for your answer. I am just once a week at uni, thats why I respond a week later sorry. So I tried it again and it still didnt work. Is it because its a NUMERIC edit field? But I didnt found anything on the internet on how else I could solve this problem :/ Could you maybe take a look at at it please?

        % Button pushed function: SinusButton
        function SinusButtonPushed(app, event)
            x = 0:0.01:15;
            plot(app.UIAxes,x,sin(x))
        end
        % Button pushed function: CosinusButton
        function CosinusButtonPushed(app, event)
            x = 0:0.01:15;
            plot(app.UIAxes,x,cos(x))
        end
        % Value changing function: Slider
        function SliderValueChanging(app, event)
              %app.Slider.Value = set(app.xEditField, 'String', num2str(Value));
              value = app.Slider.Value;
              app.xEditField.Text = sprintf('%.3f', value);
              app.yEditField.Text = sprintf('%.3f', sin(value));
        end

So this is my code. I want to create a gui to calculate a sin function. The cos was just extra, not important.

In the end the x field should give the value of the Slider and the y field should give the sin.

I would be soo sooo sooooo greatful if you or anybodyelse coul help me :)

Thank you for your answer :)

So the sine and the cosine works well, it's really just the problem with the slider. When I want to move the slider I get this error notification:

Do you know what I should try next? :)
