I am writing a code like this
if D == 0 d0_L2_pre = norm(v).^2; else d0_L2_pre = norm(v).^2/abs(D); end
I want to store the results(d0_L2_pre) in a .txt file like the way it is showing in the picture. I was trying
LastName = {'M-01';'M-02';'M-03';'M-04';'M-05';'M-06';'M-07';'M-08';'M-09';'M-10';'M-11';'M-11'}; d0_L2_Pre = [d0_L2_pre]; T = table(d0_L2_Pre,'RowNames',LastName); writetable(T,'distance.txt','WriteRowNames',true) type 'distance.txt'
And then how to save the .txt file in certain directory?
How to edit or write a new code which will write a .txt file just like the picture.

Writing that file is easy and efficient with one loop:
C = {'pre','post','shift'};
[fid,msg] = fopen('test.txt','wt');
assert(fid>=3,msg)
for k = 1:numel(C)
D = rand(1,12); % fake data
X = 1:numel(D);
fprintf(fid,'"d0_L2_%s"\n',C{k})
fprintf(fid,'"M%d" %.16f\n',[X(:),D(:)].')
end
fclose(fid);
It generates this file:

"And it creates an empty file in the directory."
Check the size of X and D.
Is the file totally empty, or does it include the header?

name={'pre','post','shift'}
A={rand(1,12),rand(1,12),rand(1,12)} %taking a random data for pre, post and shift
for kk=1:3
