Using fgetl() to read lines
显示 更早的评论
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.

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}.

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.
