Use '\n' to add a new line before writing 'blength'
clc
fid = fopen('C:\Users\Mr Andrew\Desktop\111.txt', 'a');
for k = 1:5
fprintf(fid,'alength\n blength \r\n')
end
fclose(fid);

with '\n'
the txt will be like
alength blength
alength blength
alength blength
alength blength
alength blength
but i want to be like
alength
blength
alength
blength
alength
blength
alength
blength
alength
blength

No, the '\n' between 'alength' and 'blength' will move the pointer to the next line. My output was:
alength
blength
alength
blength
alength
blength
alength
blength
alength
blength
