Here, I need to assign different operations for each drop down menu option. I have this code. I do not know how to connect the operation and the option. Can someone help me with this one? Thank you.
fig = uifigure;
dd = uidropdown(fig);
dd.Items = {'Alpha','Beta','Gamma'};
prompt = {'a :', 'b :', 'c :'};
dlgtitle = 'Parameters';
dims = [1 70];
definput = {'1','2 ','3'};
answer = inputdlg(prompt,dlgtitle,dims,definput)
a=str2double(answer{1});
b=str2double(answer{2});
c=str2double(answer{3});
%calculation for alpha
answer=a.^2+b.^2
%calculation for beta
answer=a.^2+c.^2

You can access the selected option using the Value property of dd:
switch dd.Value
case 'Alpha'
%calculation for alpha
answer=a.^2+b.^2;
case 'Beta'
%calculation for beta
answer=a.^2+c.^2;
otherwise
answer=0;
end
If you want the input dialog box to show whenever the user changes the dropdown:
fig = uifigure;
dd = uidropdown(fig, 'ValueChangedFcn', @ddChanged);
dd.Items = {'Alpha','Beta','Gamma'};
ddChanged(dd);
function ddChanged(src, ~)
prompt = {'a :', 'b :', 'c :'};
dlgtitle = 'Parameters';
dims = [1 70];
definput = {'1','2 ','3'};
answer = inputdlg(prompt,dlgtitle,dims,definput);
a=str2double(answer{1});
b=str2double(answer{2});
c=str2double(answer{3});
switch src.Value
case 'Alpha'
%calculation for alpha
answer=a.^2+b.^2;
case 'Beta'
%calculation for beta
answer=a.^2+c.^2;
otherwise
answer=0;
end
disp(answer);
end

I'm not entirely sure what you mean. The dropdown should close after you select one of its options. As long as you create the input dialog box right after creating the uifigure/dropdown, it will appear and steal the focus from the figure/dropdown. To avoid this, I included the second piece of code above, where the input dialog box only shows after the user has selected an option from the dropdown. Using callbacks (i.e. functions) to control the behavior here is probably the easiest way to do what you want. When you create a uifigure and add a dropdown, you are essentially creating a GUI. What exactly are you trying to avoid?
