I am using Matlab 2013 version and it doesn't contain grayconnected.m file in library. Can any help me out to get grayconnected.m file.

It looks like, this function is part of Image processing toolbox. You will have to buy this toolbox to be able to use the function. If you have the toolbox installed and are still getting error messages, please post the error message itself.

See my attached magic wand program, which does a similar thing.

Use the ver command to check what toolboxes you have. If you have the IPT installed, I would bet that grayconnected was not part of that TB until more recently, so you would need to upgrade to a more recent MATLAB release.
To check the above statement, I looked for when grayconnected.m was introduced, and it seems to have appeared in the current release.
That would suggest you need to get the newest MATLAB release. Note that you cannot upgrade only one toolbox.
