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

What are the problems you are facing? Your question is not clear. Could you please elaborate more about your question.

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!
