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
