MATLAB: Upload txt file for a matrix

MATLABupload file

i can make a comma delimited .txt file with 3 columns and say 5 rows. I need to make a 3×5 matrix from this file.

thank you

check out dlmread()

or textscan()

For example,

writematrix(sr, 'filename.dat') % or dlmwrite('filename.dat', sr);

Read it using these lines

filetxt = fileread('m1.txt');
filetxt = strrep(filetxt, ',', '.');
data = cell2mat(textscan(filetxt, '%f%f%f%f'))
