Creating an empty figure

I am having trouble creating a blank figure.

This is the code I currently have

tf = isempty(names);
if tf == 1
    plot()
    
elseif opt <1 | opt > 3
    plot()
    disp("Invalid opt value, it must be either 1, 2, or 3")

tf = isempty(names);
if tf == 1
    figure  % to generate empty plot 
    
elseif opt <1 | opt > 3
    figure
    disp("Invalid opt value, it must be either 1, 2, or 3")
end

To generate a blank figure use figure command. plot() function requires input arguments. close the if-else statement with keyword, end
