MATLAB: Changing the name of multiple csv files in a folder

filesloopsave

I have a folder containing 3000 csv files. All of these are named in the format: cor0.1 sc10 fc0.1_0.csv.
I want to change the name of all of these files to c0_1f0_1_0.csv.
Is there a way i can write a loop to do this for me?

hello
this is a first attempt
I prefered to create the renamed copies in a separate folder
also my code will probably need some upgrade as I don't know how the numberring inside your filenames can evolve among your 3000 files 
d = dir('*.csv')
dir_out = [cd '\out']
for ci = 1:numel(d)
    filename = d(ci).name;
    
    ind_und = strfind(filename,'_'); % search underscores 
    ind_dot = strfind(filename,'.'); % search dots 
    ind_f = strfind(filename,'f');  % search "f" 
    
    new_filename = [filename(1) filename(ind_dot(1)-1) '_' filename(ind_dot(1)+1) filename(ind_f ),...
        filename(ind_dot(2)-1) '_' filename(ind_dot(2)+1) '_' filename(end-4:end)];
    
    copyfile(filename,fullfile(dir_out,new_filename));
    
end
