Never tried to strictly define the operation? The sample gives the idea, but does not strictly describe the requirement. If you do it in a mathematically strict manner, most likely, you will see a solution. How will you define it with the arrays of the different lengths?

THis seems to ba a lot like matrix operations, and that is not implemented by defoult, unless you create your own list that inherits/implements Lift(of Double) etc, and add/overrride operators to them... This is reasonabley complicated if you have not done it before. Otherwise you could just do this by using for loops...

Please see my comment to the question. It looks like per-element subtraction. Do it in a loop. Decide what to do with the arrays of different sizes and with nulls, and then implement the desired algorithm. Ask yourself another question: what if next time it will be addition of arrays? division? multiplication? Will you need to ask your question again? :-)
