MATLAB: Save data to .txt file

To write a text file with columns of data that have variable names, use the “writetable” function. First, create the data to write, put it in a table with variable names, and then write the data to text file.

% Create two columns of data
A  = rand(10,1);
B = rand(10,1);
% Create a table with the data and variable names
T = table(A, B, 'VariableNames', { 'A', 'B'} )
% Write data to text file
writetable(T, 'MyFile.txt')

Starting in R2019a, you can use "writematrix" to write a matrix to a file.

For example:

M=magic(5);
writematrix(M, "M.txt");

For more information on "writematrix", please refer to the following documentation:

MATLAB: Export data to txt file

Change:

fprintf(fileID1,'%1.4f % 1.4f\n',velo_t1)
