title: How to translate this Math Formula in Haskell or Python? (Was translated in PHP)
body: <p>I'm trying to convert a Math Formula into PHP code.</p>
  
  <p>You can see the formula in the accepted answer here: <a href="https://math.stackexchange.com/questions/92942/applying-a-math-formula-in-a-more-elegant-way-maybe-a-recursive-call-would-do-t">Applying a Math Formula in a more elegant way (maybe a recursive call would do the trick)</a>.</p>
  
  <p>I'm not a professional coder so I'm trying my best to translate it but my skills are limited and I've encountered several problems.</p>
  
  <p>Let's start.</p>
  
  <p>There's a vector containing players' stacks: I think a bidimensional array should do the work here. I'd add a key to identify each player.</p>
  
  <pre><code>$array = array(1 =&gt; 2000, 3 =&gt; 5000 ...);
  </code></pre>
  
  <p>Now he wants to create a Matrix of values, I did my researches and found a PEAR package called Math_Matrix, installed it but I'm wondering how to create that sort of matrix.</p>
  
  <p>I'm worried that I won't be able to translate the entire code because he uses advances methods like recursive calls etc.</p>
  
  <p>Could you help me?</p>
  
  <p><em>EDIT: OLD BOUNTY REWARD</em></p>
  
  <p>I tried what you've suggested but I feel like wasting my time because of my poor-programming skills.</p>
  
  <p>I'VE DECIDED TO OFFER A 50 BOUNTY IF SOMEONE WANTS TO HELP ME BY TRANSLATING THAT FORMULA IN PHP.</p>
  
  <p>Note that if you think that translating in Python is easier/more suitable/other, please provide me a way to include the Python script inside a PHP script since I'm planning to use this formula in a website.</p>
