MATLAB: Get Values From User using Edit Field Numeric in App Designer

app designeredit field numericget values form userget values from user using edit field numeric in app designer

Hi all, I want to get values from user for 4 parameters, then place them into the second part of the code. 
% Callback function



        function LengthEditFieldValueChanged(app, event)
            global L
            value = app.LengthEditField.Value;
            L = value;
        end
        % Callback function
        function DiameterEditFieldValueChanged(app, event)
            global D
            value1 = app.DiameterEditField.Value;
            D = value1;
        end
        % Callback function
        function RPMEditFieldValueChanged(app, event)
            global n
            value3 = app.RPMEditField.Value;
            n = value3;
        end
        % Callback function
        function reciprocatingtimesEditFieldValueChanged(app, event)
            global S
            value4 = app.reciprocatingtimesEditField.Value;
            S = value4;
        end
2nd part of the question
function ButtonPushed(app, event)
            global a        
global V_f      
global L           
global S         
global n        
global D          
 
 a = 10;
V_f = 15;  
x = 1:50; %diameter
y = 1:50;   %length
V_w = (V_f * pi * D * n)/(2*L*S);
for i = 1:length(y)
    hor(i) = V_w * sqrt(2*y(i)/a);
    i = i+1;
end
plot(y,hor, 'r')
hold on
for i=1:100;
    k = y - i;
    plot(k, hor, 'r')
    hold on
     m = -x - i;
    plot(m, hor, 'b')
    hold on
    i= i +1;
end
        end
    end

Hi, Erkin in App Designer instead of using the keyword global, you can declare the variables as Public Property, which can be used inside and out of the app. The attached zip file contains the app for your reference, where I have modified your functions.
Hope this helps!
