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

The following method is based on what Jonas proposed above, which I love very much. How ever, what we get is a cell array s. rather than a single String.

I found with one more line of codes, we can get a single string variable as below:

% original codes, thanks to Jonas

fid = fopen('test.txt');
s = textscan(fid,'%s','Delimiter','\n');
s = s{1};

% the additional one line to turn s to a string
s = cell2mat(reshape(s, 1, []));

I found it useful to prepare text for jsondecode(text). :)
