Next, we apply vertical pairwise averaging and differencing to each column of the result. To complete the transformation, we repeat this process recursively only on the quadrant containing averages in both directions.
Q: Please help me rewrite the sentences.
thank you. this is an assignment for writing.
Either Ray is a LOT smarter than me or he was teasing a bit. I have absolutely NO IDEA what you are saying needs to happen. The only part I understood was doing it recursively.
I was assuming he knew what the procedure was. I don't.
What he's written is grammatical enough. It seems to make sense, and if it does describe the procedure that needs to be followed, the sentences don't need revising. I was assuming he knew the procedure but was uncertain about his sentences.
Well, I'm a little relieved that you don't know what a "quadrant containing averages in both directions" means either!
I was imagining a 2-dimensional matrix, somewhat like a chess board.
Pick any square (I took "quadrant" to mean square). There are two directions orthogonal to any square. If both the row and column in which that square is placed contains an "average", perform the procedure on that square.
Move to the next square, etc.
But that's a guess. Now you know how my mind works ;)
It would obviously be simpler if the poster had said. "I am trying to reduce a matrix", or something like that!
I really, really hated linear algebra!
