Generally speaking, summation can be done through three standard methods:
  • initializing the result to 0, and looping over all of the possibilities, adding each term to the result
  • using sum()
  • using symsum() if you have access to the symbolic toolbox. This should be used only for formula and not for specific numeric values.

So that would appear to be external information representable as an array. In that case the above code should work.
