xlsprotect() is not built into MATLAB. You need to download it and install it from the File Exchange http://www.mathworks.com/matlabcentral/fileexchange/6046

how can I install this function in MATLAB ?? can you please explain ?

[Walter Roberson]

Click on the "Download All" link on that page. Create a directory and unzip the .zip into that directory. Add the directory to your MATLAB path using pathtool.
