Print Data to .txt Files

I have some problems on printing a whole data I have into a form of txt file. It consists of 5 variables and each variable is 3116x1 double. This is the script I made.

file_out2 = fopen(sprintf('%s%s%s', dir_in, name_file(8:11), '.txt'), 'w');
fprintf(file_out2, '   MJD_gab    lat_gab    SSH_gab    SLA_gab      YYF_gab\n');  
fprintf(file_out2, '%14.8f %10.6f %10.4f %9.4f %16.8f\n', MJDgab, latgab, SSHgab, SLAgab, YYFgab);

fclose(file_out2);

In the first trial, the result came out but the variables were not printed into coloumn. It seems like they were printed 'horizontally'.

And everytime I ran the script for the second or manymore time, it always came error.

Perhaps it will work better if the script was corrected. I hope someone can help me out of this. Thank you for the help!

Put square brackets around the variables in your fprintf statement to concatenate them into a matrix, then transpose the matrix.

This should work:

fprintf(file_out2, '%14.8f %10.6f %10.4f %9.4f %16.8f\n', [MJDgab, latgab, SSHgab, SLAgab, YYFgab]');

If you have R2013b or later, an easier way would be to form a table from your data:

T5 = table(MJDgab, latgab, SSHgab, SLAgab, YYFgab, 'VariableNames',{'MJD_gab','lat_gab','SSH_gab','SLA_gab','YYF_gab'})

then use the writetable (link) function.

oh my God how could I forget that square brackets? lmao

Thank you for correcting mine and giving the alternative syntax as well, thank you so much!
