Okay, where to start?

Sounds like the beginning of a joke, you have a fancy data table, a

splendid output table and a method. You use the method to calculate a

splendid number out of the data table and store it in the output table.

Similar to taking a bean out of the jar and putting it into another

nicer jar.

How do you get the input-data-table value into the method without

passing the whole table as an argument all the time?

The problem is that I iterate the same calculation over all cells, which

is not a problem for four, nine, or 25 cells, but it could be one if

this runs on 100x100 matrices.

This maybe about basic instance/symbol/variable scoping, but I’m not

sure and so far I had avoided dealing with them. So, please, someone

needs to explain me what I actually look for, is there a better way than

passing the complete table into the method?

Thanks in advance,

the Force may be with you—always.
