body: <p>What is the syntax for declaring a global 2-dimensional array in MATLAB?</p>
  
  <p>I want the array to be blank, or uninitialized. That is, I want to be able to initialize it to some value later on using a for-loop. All the examples I have come across so far consist of initializing the array when it is declared. I find this rather tedious because my array might have to be a large one.</p>
  
  <p>Thanks. </p>
