So how do you make MAtlab into a responding program?

I Want to make a program that can respond back to you with words. I found one way but its annoying. I need to put (' ') Around the words I type and the it response but I just want to type the words and it give off a correct responses. Any good examples to make this work?

Use input with the 's' option to request the responses

din = input('What did you have for dinner?', 's');

[Rainaire Hansford]

Not exactly what i meant. What I really was looking for was if I say hello, hey or hi, it will give me a respond for either of them. For Example I have din = input(' ', 's'); if din <= 'Hello' fprintf('Hello sir'); if din <= 'Hi' fprintf('Hi there'); end end. Now it works for the first one (Hello) but when I type hi it say something like matrix error or some stuff. I want it to work for both.

[Matt Kindig]

Don't use the <= operator. The reason you get the matrix error is because din cannot have both 5 characters (as it does if din=='Hello') and 3 characters (as if din=='Hi'), as your code assumes. That is the source of your matrix size error.

Use strcmp() (or strcmpi()) instead:

if strcmpi(din, 'Hello'),
   fprintf('Hello sir');
elseif strcmpi(din, 'Hi'),
   fprintf('Hi');
end

Thanks guys it work now let say I want to make it respond to any word for ex.

if strcmpi(din, 'Hello','Hi','Whats up')

This obiviously doesnt work but I think you understand when I mean that. Like if i make any of these responds it will send back the same responds. How could i do that

[Walter Roberson]

if strcmpi(din, {'Hello', 'Hi', 'Whats up'})

[Rainaire Hansford]

Yeah that's not working like I planned any other suggestions.

[Walter Roberson]

if any(strcmpi(din, {'Hello', 'Hi', 'Whats up'}))
