MATLAB: Move to next selection

choicecontinuehelphowMATLABmenumenu functionmove onmultiplemultiple choiceselectionskip

hi all, I am wanting matlab to move to the next multi choice question if the chosen answer is "No"

eg:

choice = menu("Do you want to see the opening times of this recycling centre?","Yes","No")
if choice == 1
    new_data(selectedplaceindex,1:3)
elseif choice == 2
%THIS IS THE LINE i STRUGGLE WITH
end
choice2 = menu("Do you want to navigate there?","Yes","No")
if choice2 == 1
        new_data(selectedplaceindex,4)
elseif choice2 == 2
        menu("Thank you, keep recycling!")
end

this is the selection process I want however, after "choice" is chosen, if "choice == 2" i want matlab to forget that selection and move on. equally with choice ==1 but i think that works anyway.

so you don't need to place an else in the first:

choice = menu("Do you want to see the opening times of this recycling centre?","Yes","No")
if choice == 1
    new_data(selectedplaceindex,1:3)
end
choice2 = menu("Do you want to navigate there?","Yes","No")
if choice2 == 1
        new_data(selectedplaceindex,4)
elseif choice2 == 2
        menu("Thank you, keep recycling!")
end

Julia - all this code

if PromptMessage == 1
    Choice2 = PlayerOption(1);
elseif PromptMessage == 2
    Choice2 = PlayerOption(2);
end

seems to be doing is to select a door given the contestant's decision to either remain with his/her current decision (1) or choose the remaining door (2). PlayerOption is simply an array of the two remaining doors (Monty Hall has already opened one door and shown that there is nothing behind it) one of which is the door to the car. The author of the code is creating an array of those two doors with the first one being the door that the user has already selected. So if PromptMessage is 1, then the user will stick with his original choice and so Choice2 is the id for that door (since his/her original choice is the first in the array, the code assigns PlayerOption(1) to Choice2). If the PromptMessage is 2, then the user switches to the other door and it's id is assigned to Choice2. The code then compares this final choice to true winning door id and increments the winning or losing count appropriately.

The code may be a little easier to understand if the variables were named differently. For example,

if playerDecision == 1
    % player decides to stick with original door selection
    finalDoorId = RemainingDoorIds(1);
elseif PromptMessage == 2
    % player decides to choose the other door
    finalDoorId = RemainingDoorIds(2);
end

and

%% Determine number of wins and losses
if finalDoorId == winningDoorId
    numberOfWins = numberOfWins + 1
else
    numberOfLosses = numberOfLosses + 1
end

Wrap the whole thing in a while, and add break statements. Don't add a break if you want the code to repeat and ask the user again. That's one way anyway:

while true
  input=menu('Please pick what kind of character you want to be.',...
    'Hunter','Warrior','Mage','Demon','Elf');
  switch input
    case 1
      hunter=menu('The Hunter is a character that prefers to fight from a distance. Do you want the Hunter?','Yes','No');
      switch hunter
        case 1
          disp('Congratulation you have chosen the Hunter. Your journey is about to begin.')
          break;
        case 2
          
      end
    case 2
      disp('The Warrior is a character with a high strength.')
      break;
    case 3
      disp('The Mage is a Character that attacks with magic from a distance.')
      break;
  end
end

I also fixed misspellings of character, journey, congratulations, etc.
