Each tile contains four squares, each with a default of 10 pixels per side. The light squares on the left half of the checkerboard are white. The light squares on the right half of the checkerboard are gray.

TILE = [DARK LIGHT; LIGHT DARK]

example

I= checkerboard(n)creates an 8-by-8 square checkerboard image where each square hasnpixels per side.

example

I= checkerboard(n,p,q)creates a rectangular checkerboard image wherepspecifies the number of rows of tiles andqspecifies the number of columns of tiles. If you omitq, the number of columns defaults topand the checkerboard is square. Each square hasnpixels per side.
