How to store values of chain code in an array?

After chain code I want to store all the values in an array so that I can do comparision.

Ekta - please clarify what you mean by chain code. Are you referring to a lossless compression algorithm for monochrome images?

[Walter Roberson]

Ekta is referring to the Freeman Chain Code http://uk.mathworks.com/matlabcentral/answers/271393-how-to-update-the-value-of-next-pixel-in-chain-code . Everyone who asks here about chain code without specifying a different chain code is referring to Freeman Chain Code. Universities these days are either teaching that it is the only chain code, or else they are teaching that being vague about questions is desirable.
