MATLAB: Print a line from a .txt

MATLABtext;txt

Imagine that you have a .txt with 50 lines and you want your program to print the line 33 of the .txt.

I know that first i have to open the file using fid=fopen(…); but then I don't know how to print only the line I want. Can somebody help me please?

for K = 1 : 32
  fgetl(fid);
end
line33 = fgetl(fid);

Hi!

count = 1;
tline = fgetl(fid01);
while ischar(tline)
count = count + 1;
disp(tline)
if count == 3
fprintf(fid02,'%s\r\n',tline);
end
tline = fgetl(fid01);
end 
fclose(fid01);
fclose(fid02);

You can do as well

for n = 1:3
tline = fgetl(fid01);
end
fprintf(fid02,'%s\r\n',tline);
fclose(fid01);
fclose(fid02);

Vadim - try using fprintf. For example,

 % open your file for writing
 fid = fopen('myTextFile.txt','wt');
 % write the matrix
 myData = randi(255,10,3);
 if fid > 0
     fprintf(fid,'%d %d %d\n',myData');
     fclose(fid);
 end

The above is a very simple example that is based on the examples in the provided link so see that link for more details.
