Hello,
I have a 7x1 variable ("X1") to which I need to add a row at the beginning (cell value = 0) and a row at the end (cell value = 0). Obviously, I could do this manually, but I have many variables this needs to be done to.
My noodle is fried today. Apologies.

The easiest way is to concatenate zeros at the beginning and end of ‘X1’:
X1 = randi(9, 7, 1); % Create Data To Test Code
Result = [0; X1; 0];

The X1 = randi(9, 7, 1) was just to get some sample data. You can eliminate that line since you already have X1 with your actual data. Just do this:
Result = [0; X1; 0];
