Hi,

I am simulating an animal, which moves like the king on a chess board. I want to make a matrix looking exactly like the illustration here:

http://en.wikipedia.org/wiki/Chebyshev_distance

The purpose is to calculate the distance from the animal's position to every square on the board.

I have made this pseudocode::

%------------------------------
x = boardSizeX; %column size
y = boardSizeY; %row size

position = [posX, posY]; %position of animal

indices = transpose([1:x 1:x 1:x ... ; ones(1,x) 2*ones(1,x) 3*ones(1,x); ... ]) % ... means y times
distances = pdist2(indices ,position ,'chebychev');
distanceMatrix = reshape(distances,x,y);
%--------------------------------

This is not very elegant. Does anyone have any idea of how to make it a little more elegant?

Thanks!
