Opposite command of strfind?

I have a general question. Does it exist the opposite command of strfind ?

[Les Beckham]

What would this "opposite" command do? Please give an example showing sample inputs and output. Or, at least give a more complete explanation in words.

[Ivan Mich]

for example, strfind shows true result for words: "Milano" and "Milano".

I would like to have a command that could detect in an array the non same words...

No, strfind does not replie true for any inputs. It replies the indices of found matchs.

Maybe you mean:

a = "Milano";
b = "Milano";
~isequal(a, b)
~strcmp(a, b)
isempty(strfind(a, b))
a ~= b
~(a == b)
~contains(a, b)  % or (b, a) ?
