Are you sure you don't already have the file open in Excel? If so, it won't let you save it while it's already open. I know starting with Windows 7 there are a lot of folders that you cannot save to any longer, such as anything under the Program Files folder, and sometimes others that you wouldn't think should have such a restriction, like C:\Users and C:\ProgramData, though C:\Users\nkumar\Documents would be allowable.

You are trying to write into a directory you do not have permission for. You can get that if you are trying to save under the MATLAB installation directory instead of into your own directory.
