If statement comparing strings

I want to do this:

if 'Word1' == 'Word2' 'do something' end

'Word1' and 'Word2' aren't necessarily going to be the same amount of characters.

Everything I try ends in "eq error".

How do I do this?

[Walter Roberson]

strcmp('Word1', 'Word2')

OR

all(size('Word1') == size('Word2')) && all('Word1' == 'Word2')

OR

isequal('Word1', 'Word2')

Hi I have a similar question. I type:

if isequal(x,'a') && isequal(x,'p') && isequal(x,'T')==0

       fprintf('ERROR:You entered incorrect choice.')

but it doesn't work

[Walter Roberson]

if ~ismember(x, {'a', 'p', 'T'))
  printf('ERROR:You entered incorrect choice.');
end

or

if ~(isequal(x, 'a') || isequal(x, 'p') || isequal(x, 'T'))
  fprintf('ERROR:You entered incorrect choice.');
end

or

if ~(strcmp(x, 'a') || strcmp(x, 'p') || strcmp(x, 'T'))
  fprintf('ERROR:You entered incorrect choice.');
end

or

if ~strcmp(x, 'a') && ~strcmp(x, 'p') && ~strcmp(x, 'T')
  fprintf('ERROR:You entered incorrect choice.');
end

or

if ~any([strcmp(x, 'a'), strcmp(x, 'p'), strcmp(x, 'T')])
  fprintf('ERROR:You entered incorrect choice.');
end
