Re: Reading file

Agree with the XY-problem.

Anyway, when speed is important, never grow an array inside a loop by appending. Pre-allocate a decent amount of memory and only increase in chunks when necessary. When outside the loop, cut the array to size.

Do you really need a 2D array? Try reading it as one big string (as suggested) and use strsplit to obtain a cell array of strings.

Just cut it after reading with fread:
T = T(:,1:80);

Btw, this all sounds like a XY-problem: http://xyproblem.info/
