I have to make an if elseif else statement where if pertains to three options I put

    answer=menu('Select a curve type','a) Square wave','b)Sine wave' ...
               ,'c)Cosine wave','d)Tangent curve','e)Decaying exponential');
        if answer==1,2,3
            frequency=input('Enter a frequency');
            amplitude=input('Enter an amplitude');
            cycles=input('Enter a number of cycles');
        elseif answer==4
            frequency=input('Enter a frequency  \n');
            cycles=input('Enter a number of cycles  \n');
        else answer==5
            tau=input('Enter a time constant');
        end

what should I do to make it work?

在 MATLAB Online 中打开

if any(answer==[1,2,3])
  frequency=input('Enter a frequency: '); 
  amplitude=input('Enter an amplitude: '); 
  ccycles=input('Enter a number of cycles: '); 
elseif (answer==4) 
  frequency=input('Enter a frequency: '); 
  cycles=input('Enter a number of cycles: '); 
elseif (answer==5)
  tau=input('Enter a time constant: '); 
else
  error('some error');
end
