Read a whole text file into a MATLAB variable at once

Question

I would like to read a (fairly big) log file into a MATLAB string cell in one step. I have used the usual:

s={};
fid = fopen(\'test.txt\');
tline = fgetl(fid);
w         


        

Answer 1

I tend to use urlread for this, e.g.:

filename = 'test.txt';
urlname = ['file:///' fullfile(pwd,filename)];
try
    str = urlread(urlname);
catch err
    disp(err.message)
end

The variable str then contains a big block of text of type string (ready for regexp to operate on).
