[OctDev] Suport octave rescursive function?

From: Pedro A. F. M. <pfr...@fa...> - 2005-11-07 08:48:17

Hi all,
    Suport octave rescursive function? In this case, how can I implement 
it? I'm trying something like that:
        function res = test(a)
            if (a>0)
            j = test(a)
                res = a + j,
            else
                res = 0;
            endif
        endfunction
    but it's fauls...
       Pedro

Yes.

Please post a working example of your code (that is, a stripped down
example of the failing code). Otherwise it's just guessing.

I posted my code in last mail... the code was:<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; function res = test(a)
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (a&gt;0)
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; j = test(a)
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; res = a + j,
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; else
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; res = 0;
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; endif
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; endfunction
<br>
upssss.... line 4 "j = test(a)" must be "j = test(a-1)"... it was the
error of my code... :-* sorry and thanks for all.<br>
&nbsp;&nbsp;&nbsp; Regards,<br>
&nbsp;&nbsp;&nbsp; Pedro<br>

I think there's a bug in your function: if a is positive, then the function
"test" will get called again and again until you reach max_recursion_depth,
which is 256 by default.
