Too many input arguments for function not called in live script

Hello

I am trying to use a windowing function and I am using a live script. I have the various window function handles as a drop down and I am generating windows based on the drop down value.

% Various Orders of FIR
min_ord = 3;    % This is a slider
max_ord = 5;    % This is a slider
cutoff = 75;    % This is a slider

options = [];
windowf = @chebwin; %This is a drop down
% These three windows require an input
if isequal(windowf, @kaiser)
    options = 0.5; % Beta value
elseif isequal(windowf, @chebwin)
    options = 50; % Sideband Attenuation in dB
elseif isequal(windowf, @tukeywin)
    options = 0.44; % Ratio of taper to constant section
end

h_arr = []; wh_arr = [];
out_arr = [];
gp_arr = []; wgp_arr = [];
for i = min_ord:1:max_ord
    windowvals = [];
    if isempty(options)
         windowvals = window(windowf, i+1)
    else
        windowvals = window(windowf, i+1, options);
    end
    b = fir1(i, cutoff/(fs/2), "low", windowvals);  
    
...

Now when I run this code, I am getting the following error

Error using barthannwin (line 24)
Too many input arguments.

This happens even if the selected window is not Bartlett-Hann. I have even tried to remove Bartlett-Hann from the drop down options and I am still gettting the same error. I am not sure how to fix this. Is there a workaround?

Hi

I replicate your code, its working in my case. You have not defined the variable fs, also did not put end after for loop. For your 2nd query, try to clear the variable and again run the code. It will work.

Hope it will help!
