Recursivity with MathScrip

[Pierre_]

Hello,

I would like to use mathscript to code some recursive function,

So, I tried to code the classical factorial function :

---

function answer = factorielle(n)
    if( n == 0 )
        answer = 1;
        return;
    else
        answer = n*factorielle(n-1);
    end

---

But it seems that it is not working...
Is my code wrong ? or is recursivity not working ?

Thank,
Pierre

Hi Pierre,

Unfortunately, MathScript does not support recursive functions.  There is, of course, a function called factorial that computes the factorial of a given number.  But I suspect this is not what you are trying to accomplish.  You have also discovered a bug in that we do not report an error message on an attempted recursive function call.  This makes the function appear to work and just fail to return a value.  We are aware of the lack of support for recursive functions and are considering adding support for them in a future version of MathScript.  For now, you can try to implement your recursive function with an iterative method.
