movefile() is used to move or rename file or folders
you can use something like below
files=dir('re180M_*'); %get files whise name starts with re180M_
for i=1:numel(files)
j=100;
newname=strcat('re180M_',num2str(j)); %assign new name
movefile(files(i).name,newname); %rename the file with new name
j=j+1;
end
Hope this helps!
