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!
