Hi everyone,

I am trying to have a multiple-choice questionnairequestionnaire, that will go to the next step (in this case, the next question) depending on what you answer.

What is the best approach for this? I was thinking of using an if-else statement; however, I don't know how to have a multiple choice question.

I really hope you guys can help me with this!

Thank you

Do you want to use a GUI, or do you want a linear program that uses only the command window?

whichever one is better, I have never used GUI, but if it's better then I don't mind using it.

Neither is intrinsically better than the other. For a 'normal' function you should probably use functions like menu or listdlg. It depends on how complicated your question tree is how complicated your code will get.

Take a look at all the dialog functions in matlab like questdlg, listdlg etc.

Start however drawing a graph of all the questions and the paths to the next questions depening on the answers. In your code you can use if-else-end or, even better, switch-case-end constructs

answer = questdlg(...)
switch answer
    case 'A' % ask follow-up 1
    case 'B' % ask follow-up 2
    otherwise
end
