how assign cell to dropdown menu

app.PeriodicityDropDown.Items

ans =

  1×4 cell array

    {'Option 1'}    {'Option 2'}    {'Option 3'}    {'Option 4'}
    
   K>> class(tmp)

ans =

    'double'
    
i try this solution:
    

K>> app.PeriodicityDropDown.Items={tmp}
'Items' must be a 1-by-N cell array of character vectors or a string array.
 
K>> app.PeriodicityDropDown.Items=num2cell(tmp)
'Items' must be a 1-by-N cell array of character vectors or a string array.

how can i assign it?

Did you try converting the numeric to a string array or to a cell array of character vectors?

Hi Luca,

I understand that you are trying to set the Items property of a dropdown component in a MATLAB app with numerical values, but the dropdown requires a cell array of character vectors or a string array.

Here is how you can convert your numerical array to a suitable format:

1. Convert the numerical array to a cell array of character vectors:

%If tmp is your numerical array, you can convert it to strings first and then to a cell array:
tmp = [1, 2, 3, 4]; % Example numerical array
tmpStr = arrayfun(@num2str, tmp, 'UniformOutput', false);
app.PeriodicityDropDown.Items = tmpStr;

2. Convert the numerical array to a string array:

%Alternatively, you can convert the numerical array directly to a string array:
tmp = [1, 2, 3, 4]; % Example numerical array
tmpStrArray = string(tmp);
app.PeriodicityDropDown.Items = tmpStrArray;

I hope this helps!
