Hi,

I'm trying to save multiple .txt files from one single matrix on workspace ('My_matrix'). My_matrix has 480 lines and 116 columns. I'd like to have 116 .txt files, each one containing two columns, the first column for all the 116 files is the same [1,2,...,480] and the second column is the first, second,...,116th column of My_matrix.

Thank you in advance for your kind attention.

Eduardo O.

在 MATLAB Online 中打开

X= 1:size(My_matrix,1); 
for it=1:size(My_matrix,2)
    filename = ['Mytext' num2str(it) '.txt'];
    data = [X' My_matrix(:,it)];
    dlmwrite(filename,data,'delimiter','\t','precision',3)
end
