Reading Multiple script files containing numbers and text, file format is not any specific format

6 views (last 30 days)
I have 365 files each day one file so the data is of one year. File is not of any fixed format like .dat or .xls or any other fixed format.
I can import it using import option one by one, But i would like to import or read them at one go all together in a loop which is creating a problem.
Each file contains six columns, separated with a space between them as shown below
473342400 17.41726119594118 78.55087294003569 441.657340252 0.0350254898955 HYDE

I want to read these files at one go.
Please help me.

If you have 2014a then you dont have the datastore function, you should upgrade to a newer version if you can. Otherwise, here is how todo it in a loop:
Folder = 'D:\files'; % Your folder with data files
FileList = dir(fullfile(Folder, '*'));
FileList(ismember({}, {'.', '..'})) = []; % Remove . and ..
%% Setup the Import Options
opts = delimitedTextImportOptions("NumVariables", 6);
% Specify range and delimiter
opts.DataLines = [1, Inf];
opts.Delimiter = " ";
% Specify column names and types
opts.VariableNames = ["Var1", "Var2", "Var3", "Var4", "Var5", "Var6"];
opts.VariableTypes = ["double", "double", "double", "double", "double", "char"];
opts = setvaropts(opts, 6, "EmptyFieldRule", "auto");
opts.ExtraColumnsRule = "ignore";
opts.EmptyLineRule = "read";
opts.ConsecutiveDelimitersRule = "join";
opts.LeadingDelimitersRule = "ignore";
data = [];
for f = 1:numel(FileList)
file = fullfile(FileList(f).folder,FileList(f).name);
data = cat(1,data,readtable(file, opts));

Have you tried a datastore?
folder = 'D:\files'; %this is folder where the data files are
ds = datastore(folder);
data = readall(ds);

It is showing error
Undefined function 'datastore' for input arguments of type 'char'.
and readall is not to be seen in my help readall
