You have to download the function from the link: http://www.mathworks.com/matlabcentral/fileexchange/56414-xyz-file-functions/content/xyz%20file%20operations/html/xyz2grid_documentation.html

Already you have asked a question and Chad Greene explained you with link. Again you posed a question...

Actually sir I don't know to implement it in matlab. I have downloaded the file.But don't know how to use it.

Download the .zip. Unzip it into a convenient directory that is not under the MATLAB installation path. Use the MATLAB command pathtool to add the directory to your MATLAB path. You can now use the function.
