how to make it into for loop

Hello,

I am trying to make the below cose into a for loop

Would you help me with that?

file1=load('0.txt','-ascii');

a=file1(:,1);

b=file1(:,2)-r_peak1(1)/1000;

c=file1(:,3);

data=[a,b,c];

save('0.txt','data1','-ascii');

file2=load('3.txt','-ascii');

a=file2(:,1);

b=file2(:,2)-r_peak1(2)/1000;

c=file2(:,3);

data=[a,b,c];

save('3.txt','data1','-ascii');

file3=load('6.txt','-ascii');

a=file3(:,1);

b=file3(:,2)-r_peak1(3)/1000;

c=file3(:,3);

data=[a,b,c];

save('6.txt','data1','-ascii');

file4=load('9.txt','-ascii');

a=file4(:,1);

b=file4(:,2)-r_peak1(4)/1000;

c=file4(:,3);

data=[a,b,c];

save('9.txt','data1','-ascii');

Thank you

iPeak = 0;   % [EDITED]
for k = [0, 3, 6, 9]
  name = sprintf('%d.txt', k);
  data = load(name, '-ascii');
  iPeak = iPeak + 1;
  a = data(:,1);
  b = data(:,2) - r_peak1(iPeak) / 1000;
  c = data(:,3);
  data = [a, b, c];
  save(name, 'data', '-ascii');
end

but what about the r_peak(...)

it should also continue 1,2,3,...

ok i worked it out

Thank you very much
