Creating a question box with more than 3 options.

I need to create a question box with 5 options, namely, 'residential', 'office', 'toilet', 'education' and 'storage'.

I know that in Matlab, the highest number of options available for the questdlg() is 3.

Any suggestions?

Hi Joseph, I think I'm doing this exact question. Do you happen to have the final code?

Use listdlg instead.

https://www.mathworks.com/help/matlab/ref/listdlg.html

Example (selectionMode is set to only allow 1 selection).

spaceList = { 'residential','office','toilet','education','storage'}; 
[idx, tf] = listdlg('ListString', spaceList,...
    'SelectionMode', 'Single', 'PromptString', 'Select item', 'Initialvalue', 1,'Name', 'Make choice')

Now you can identify the space chosen by

if tf
    space = spaceList{idx}; 
else
    % user canceled or closed dialog
end

Am I able to make a string array to store these?

I am trying to make it so that each space in a building has a type, 'education' etc. I need to give each space a type, from a given number of spaces from a given number of floors of a building, each floor having a number of spaces. If that makes sense? I would like the output to look something like this:

[Toilet Eductation Office Office Office

Office Office Office Toilet Education]

etc.

With the [1,1] being the first space of the first floor.

I realise that this is really messy so I apologise.

You could store the results in a cell array where each element of the array contains a list of spaces for a single floor.

I updated my answer to show how to access the chosen string.

Here are examples

allSpaces{1}{1} =  spaceList{idx};    %store first floor, first space
allSpaces{1}{2} =  spaceList{idx};    %store first floor, 2nd space
allSpaces{2}{1} =  spaceList{idx};    %store 2nd floor, 1st space

If you're not assinging the spaces in order for each floor, you'll need to allocate each element of the cell array to avoid indexing errors. This will require you to know the number of spaces per floor.

Say the number of spaces for the 1st, 2nd, 3rd, and 4th floors are [5 4 5 6] respectively,

% Allocate cell array with empty strings
spacesPerFloor = {5 4 5 6}; 
allSpaces = cellfun(@(x)repmat({''},1,x), spacesPerFloor, 'UniformOutput', false)

allSpaces =
  1×4 cell array
    {1×5 cell}    {1×4 cell}    {1×5 cell}    {1×6 cell}
    
allSpaces{1} =
  1×5 cell array
    {0×0 char}    {0×0 char}    {0×0 char}    {0×0 char}    {0×0 char}

I'm new to Matlab so that looks quite confusing, but I'll give it a go.

Thanks for the help!

Here's an example of a cell array

c = {'kitchen', 'livingroom', 'hallway'}; 

You're storing a cell array within a cell array like this.

floorLevel{1} = {'kitchen', 'livingroom', 'hallway'}; 

To see a list of all spaces in floor level 1,

floorLevel{1}
%ans =
%  1×3 cell array
%    {'kitchen'}    {'livingroom'}    {'hallway'}

To see space number 1 within floor level 1,

floorLevel{1}{1}
%ans =
%    'kitchen'

It now works perfectly. Thank you for the help!
