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

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
