Importing dat files as a double matrix

I am new in matlab, and I got data stored as dat files and I need to import them as a double matrix

Thanks in advance

That the file has a .dat extension doesn't say anything about the format of the data it contains. Please upload one of the files (using the paperclip button), so we can see what's what.

I tried to upload one of the files, but the website site refused as they don't support Dat files. I got a set of dat files and they were generated from another Matlab function. each file contains 4 columns (X,Y,U,V)

You can zip the dat file(s) and upload the zip file.

Example

#Edited (Pls Check Comments)

data = readmatrix('yourfile.dat');
data = double(importdata('yourfile.dat'));

Avoid LOAD for text data.

Avoid IMPORTDATA for text data.

Recommended: READMATRIX, READTABLE, etc.

I tried the below command

Vec00001 = readtable("C:\Users\Desktop\results\Post\Vec00001.dat", opts);

but how read the whole set of dat files? I got 1500 dat files and I need to import them all

If readtable() works for you, then see the 2nd method using dir() - https://in.mathworks.com/help/matlab/import_export/process-a-sequence-of-files.html

Yes, thank you all....I missed it.

I used the below command and it read the dat files as a table (1x1500 cell) and each cell include (65536x4 table)

for k = 1:1500

myfilename = sprintf('Vec%05d.dat', k);

mydata{k} = readtable(myfilename);

end

then I tried to convert the table to matrix, but it doesn't work, could you please correct it to me?

for k = 1:1500

mydata1(:,:,k)= table2array(mydata{:,k})

end

[Stephen23]

P = 'absolute or relative path to where the files are saved';
N = 1500;
C = cell(1,N);
for k = 1:N
    F = sprintf('Vec%05d.dat',k);
    C{k} = readmatrix(fullfile(P,F));
end
A = cat(3,C{:});
