Hi all,
I have a 2D grid as shown below where each cell represents a pair of and where and . I would like to construct a new index that combines these two indices to run over all of the cells as a one continous number.
Any help would be appreciated.
Thanks.

Consider using linear indexing. You can find an explanation towards the middle of this page. It is also explained here. If you need to go back and forth between a linear index and row/column indexing, you can use the functions ind2sub and sub2ind.

Yet again, however, I'd almost wager it isn't the most fruitful approach to the problem...
