Re: "find" equivalent for strings?

[Søren Hauberg]

Hi,
If you have Octave-forge you can do something like this

function out = is_bob(name)
        out = strcmp(name, "bob");
endfunction

cellfun("is_bob", x);

which gives you:

ans =

{
  [1,1] = 1
  [1,2] = 0
  [1,3] = 0
  [1,4] = 1
  [1,5] = 1
}

Hope that's what you look for
