Hello, How can I resize the table, I mean fill out missing values in column A so that the pattern repeat itself. For example, 0 1 2 3 0 1 2 3.........
And then replace the corresponding rows to these values by NaN in column B and C. After resizind it, the table will have 97 rows it currently has 86 rows.
Thank you!

Here's one way, using a table:
t = readtable('file.xlsx');
disp(t);

Thank you,
The main point is to fill in the missing number from column 1 so the pattern continue as 0 1 2 3 0 1 2 3 0 1 2 3 until the end.
