how to draw a checkerboard with 9 squares each with 0.5 dimension?

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

I would assume that MATLAB won't allow you to create a checkerboard with an odd number of squares due to the fact that by definition checkerboards have an even amount of squares on a side. The easiest way would most likely by to create a logical matrix representing the squares and calling image().

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?

ya, kind of. but there is an extension to this part of question.

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'?

[dinesh varma penmetsa]

it means that I need a square with 0.5 as a length of a side

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.
