I have a matrix 'b' with 1201 rows and 1 column(1203x1), but the last row is not needed and I want to delete the last row making it (1200x1).
Can I use any function for this?
Thank you

Not sure if you have a 1201x1 or a 1203x1. But to delete the last row:
b(end,:) = [];
To retain the first 1200 rows:
b = b(1:1200,:);
If b is 1201x1 these will give the same result.
Since you have a column vector I really didn't need the : for the columns, but decided to include it since that form will work for a matrix also.
