How do you mathmatically modify a coordinate in an array? Not what the coordinate references, e.g. a pixel intensity value, but the coordinate itself.

How do you mathmatically modify a coordinate in an array? Not what the coordinate references, ex. a pixel intensity value, but the coordinate itself.

So if I want to create a loop that performs a function on a point then moves to the next point by adding one to the previous coordinate:

e.g.from A(1,1) to A(1,2)

You do not want to do this "mathematically". You want linear indexing

[Ross Laws]

How would I then go about modify that though? From say A(1) to A(3) to A(5), moving along by 2 each time?

Thanks for the reply, Ross
