title: 2D array vs 1D array
body: <p>I have read the question for <a href="https://stackoverflow.com/questions/1242705/performance-of-2-dimensional-array-vs-1-dimensional-array">Performance of 2-dimensional array vs 1-dimensional array</a></p>
  
  <p>But in conclusion it says could be the same (depending the map own map function, C does this automatically)?...</p>
  
  <p>I have a matrix wich has <em>1,000 columns and  440,000,000 rows</em> where each element is a <em>double</em> in <code>C#</code>...</p>
  
  <p>If I am doing some computations in memory, which one could be better to use in performance aspect? (note that I have the memory needed to hold such a monstruos quantity of information)...</p>
