Hello everyone, I have a csv file (9X15). At the 15th column, I have times and I converted them in seconds. How can I add/save these results (from the command window)into a new column (16th) at the same csv file.? Thank you very much

Stitch the column onto the right side, and then call csvwrite():
m16Cols = [m15Cols, column16]; % Stitch column16 onto existing 15 column matrix.
csvwrite(filename, m16Cols);

You didn't say they were tables before. Try using join() or outerjoin(), but it should work as is. Then use writetable() instead of csvwrite().
What are the data types of m15Cols and column16? They should both be tables. Evidently one of them is NOT a table - it's probably a regular double vector or something. Here is a demo:
load patients % Load built-in demo data.
T4 = table(Age,Height,Weight,Systolic, ...
'RowNames',LastName)
T1 = table(Diastolic)
Tboth = [T4, T1]
writetable(Tboth, filename);
