MATLAB: How to make a string == one string in a cell array

botcellscript

I need to make a chatbot for an assignment and im having trouble with this part of the script

 x = input('+ ', 's');
 if x == {'hey','hi','hello'};
    disp('Hello')

So if the user says hi, hey or hello, the script will print hello.

But when I type in, for example, 'hey' I get the error

Undefined function 'eq' for input arguments of type 'cell'.

Error in Bot (line 3) if x == {'hey','hi'};

Cheers

Best Answer

x = input('+ ', 's');
s={'hey','hi','hello'};
if ismember(x,s)
  disp('Hello')
end

MATLAB: How to get different input, depending on the last input

ali - you could use a while loop to get the user to say/input 'hello' and then branch off to the next step which would be to get the name. Something like

 x          = input('+ ', 's');
 s          = {'hey','hi','hello'};
 userIsRude = false;
 while ~ismember(lower(x),s)
   userIsRude = true;
   disp('Don''t you say hello?');
   x = input('+ ', 's');
 end
 if ~userIsRude
     disp('Hello, What''s your name?');
 else
     disp('Finally...you said hello.  What''s your name?');
 end

You could then add the code to get the user to enter his/her name.

        case 'Brachiosaurus'
            if strcmp(bro,'Velociraptor')||strcmp(bro,'Stegosaurus')
                win=sprintf(wf,me,bro);
            else
                win=sprintf(lf,me,bro);
            end
    end
end
end

You should not use strcmp in case after switch. Please read the documentation of switch.
