Read text file in matlab (data trancation)

Question

I am reading a text file in matlab . Here is the code

allData = textread(file\', \'%s\', \'delimiter\', \'\\n\');

numericalArray = cellfun(@(s) ss         


        

Answer 1

There are various ways to read this sort of data (space-delimited). In all methods precision is preserved.

Assuming you have the input in demo.txt:

Method 1: simple textscan

fid = fopen('demo.txt','r'); % open for reading
txt = textscan(fid,'%s','delimiter', '\n'); txt = txt{1}; % read lines and unbox
fclose(fid);

H = strsplit(txt{1},' '); % split the headers line
V = str2double(strsplit(txt{2},' '));

Method 2: dlmread

R = dlmread('demo.txt',' ',1,0); % this is an example in the documentation of dlmread

Method 3: readtable

T = readtable('demo.txt');
