newstr = 'Newname';
dinfo = dir('*.mat');
for K = 1 : length(dinfo)
  thisfile = dinfo(K).name;
  [pathstr, base, ext] = fileparts(thisfile);
  if strncmp( fliplr(base), fliplr(newstr), length(newstr) )  %compare ends
    continue;  %this one has already been renamed
  end
  newfid = fullfile(pathstr, [base newstr ext]);
  movefile(thisfile, newfid);
end

Hi Walter Roberson , I have a another doubt : Except 2 files in my directory I need to rename all files.... can you please help the same.

[Walter Roberson]

folderinfo = folderinfo(~ismember({folderinfo.name}, {'.', '..'})); %remove directories . and ..

but adapt that for dinfo and the two names you want to leave alone
