## Homework Statement

PROBLEM STATEMENT:

"Represent the grid patterns in the figure with a dither matrix."

(Figure: https://www.docdroid.net/OMLUX5v/figure.pdf )

ANSWER (FROM MY BOOK):

http://www.wolframalpha.com/input/?i={{0,2},{3,1}}

## Homework Equations

Matrix_element_where_dot_should_be_printed_or_something_like_that = D_n(i,j)

i = x mod n

j = y mod n

## The Attempt at a Solution

The closest I seem to get to understand how to do the problem from my book is with page 12 (of 15) from a document I found online ( https://www.cs.princeton.edu/courses/archive/fall00/cs426/lectures/dither/dither.pdf ), but I don't understand what trunc(x,y) and P(x,y) are, and I suspect I(x,y) means the intensity at a point (x,y), but what that means, more specifically, is beyond my current understanding.

I'm VERY confused, so any input that could help me fully understand how to do the problem from my book would be GREATLY appreciated!

P.S.

If you want more information from me for anything, just let me know.
