The problem is that you're missing "endif". Typing "help if" at the 
Octave prompt gives
*** if:

 -- Keyword: if (COND) ... endif
 -- Keyword: if (COND) ... else ... endif
 -- Keyword: if (COND) ... elseif (COND) ... endif
 -- Keyword: if (COND) ... elseif (COND) ... else ... endif
     Begin an if block.
          x = 1;
          if (x == 1)
            disp ("one");
          elseif (x == 2)
            disp ("two");
          else
            disp ("not one or two");
          endif

For example:
octave:6> if (1) "it works!" endif
ans = it works!
