so here's the problem, i have a text file named sampletext.txt containing:
Hello Word
1 2 3 4 5 6
,I used the code
fid = fopen('sampletext.txt');
A = char(fread(fid,inf)).';
L = length(A)
the expected output is 22 but is outputs 23, it counts enter as 2 character. please help. :)
thankyou!

The character you call "enter" can be char([13, 10]) for DOS formatted ASCII text. Then counting this as 2 characters is correct. Why do you think this is wrong?
But could open the file under Windows in text-mode:
fid = fopen('sampletext.txt', 'rt');
Then the line reak is converted to a char(10) implicitely. But this has the disadvantage, that is does not apply the same conversion under Linux. Writig platform dependent code is a bad programming practize, so I'd rely on counting two bytes as two characters.

Why not simply use fgetl() if you want to read line by line?

@Image Analyst: Jaybee did not say, that the file should be read line by line.

No but I just offered as a possibility in case he wants to and to not have to worry about 10s and 13s.
