While trying to write in a.txt or .csv file, I am receiving the message "Index exceeds the number of array elements (0)"

I am trying to wite my output into a .csv file and a .txt file after scaning the attached .txt file (imported_PEVT.txt). However, I am getting the following error " Index exceeds the number of array elements (0)". Could anybody please help me in this regard? Thanks.

function main

fid = fopen('imported_PEVT.txt', 'r');
y = [];
m = [];
d = [];
h = [];
mm = [];
v = [];

while feof(fid) == 0

tline = fgetl(fid);
out = sscanf(tline, '%d %d %d %d %d %f');

y1 = out(1);
m1 = out(2);
d1 = out(3);
h1 = out(4);
mm1 = out(5);
v1 = out(6);


y = [y; y1];
m = [m; m1];
d = [d; d1];
h = [h; h1];
mm = [mm; mm1];
v = [v; v1];

end

write_output_file_pevt_notime('pevt_no_t.csv', v);
write_output_file_pevt_wtime('pevt_w_t.txt', y, m, d, h, mm, v);

end

function write_output_file_pevt_notime(fname, v)

fid = fopen(fname, 'w');


fprintf('%f\n',[v]');
fprintf(fid,'%f\n',[v]');    

fclose(fid);

end

function write_output_file_pevt_wtime(fname, y, m, d, h, mm, v)

fid = fopen(fname, 'w');


fprintf('%d %d %d %d %d %f\n',[y m d h mm v]');
fprintf(fid,'%d %d %d %d %d %f\n',[y m d h mm v]');    

fclose(fid);

end

The above code is working fine for me. May I know which version of matlab you are using?

Hi @bharath pro, Error was because of the a empty line in my .txt file. @SC pointed out that. Thanks both of you a lot. I am using Mathlab 2019.

The last line in your text file (line:78889) is an empty line

clear that out & your code works!

Yeah, it works. Thanks a lot.
