I tried it by using the checkerboard command but it only gives us a even number of squares.

dinesh - please clarify 0.5 dimension means. I'm guessing it has something to do with the dimension of each square in the checkerboard but you will need to provide more information. Also, is this homework?

You cannot create an image with pixels of dimension 0.5. The dimension of a pixel is always 1. Or what do you mean by 'with dimension 0.5'?

You can't have half a matrix element, but you can define the "width" of the element to be 0.5 or whatever you want. Then just use repmat(). First create one dark/light pair on one line. Then use repmat() to make a complete line. Then use repmat again to make a "band". Stitch together a band with a band of the opposite colors to get a band pair, like the top two rows of a chessboard. Then use repmat again to make as many vertical pairs as you want.
