title: Matrices in Objective-C
body: <p>Is there any class for Matrix support in Objective-C? By Matrix I mean 2D-arrays.</p>
  
  <p>What I do now is using 2 <code>NSArray</code>s, one within the other. This works perfectly but my code looks like a big mess.</p>
  
  <p>I have also tried to use C-style arrays within each-other (<code>matrix[][]</code>) but this approach doesn't fit my application as I cannot automatically <code>@synthesize</code> or specify <code>@properties</code> for them.</p>
  
  <p>I could of course create my own class for that, but what I'm wondering is if Objective-C already has something for this kind of situations. I did some Google-research but didn't find anything.</p>
