Using fgetl() to read lines

How can I choose different line to read instead first line, using fgetl() formula?

Thank you.

http://www.mathworks.com/matlabcentral/newsreader/view_thread/297814 may be of some help. Unless you are constrained to using fgetl() for some reason,

C = textscan(fid, '%s','delimiter', '\n');
% Setup the line number in LineNum,
RelevantLine=C{1}{Linenum};

should do the trick.

Thak You, I used this function, and it's working freat. It's very usefull that it's save as char.

I have one more question, can I choose two lines to read like second and third in one time, how can I do it?

I agree with Walter that this stores the entire file into the cell array, and isn't technically skipping lines. You could possibly choose more lines by using strcat on C{1}{LineNum1} and C{1}{LineNum2}.

Thank You I will remember that.

There is no method at the operating system level to position by line. The operating system itself uses fgetl() (or fgets()) to move forward by lines. MATLAB does not provide any "wrapper" over fgetl() to support skipping lines.
