What is the best way to create a 10x11 matrix from a 2x100

First column of the 2X100 matrix is a sequence of 10 numbers repeating 10 times. The final matrix required is a 10x11 matrix where first column is the sequence of the 10 numbers that repeat, the remaining 10 columns are the respective numbers from the 2nd column of the original 2x100 matrix

Sounds a lot like homework but I'll take you at your word it's not because you didn't tag it as homework.

first10 = m(1:10, 1);
column2 = reshape(m(:, 2), 10, [])
output = [first10, column2]

where m is your 100 by 2 matrix.

Thank you. I am using this method.

Let A - your matrix [100 x 2]

b = sortrows(A);
out = [unique(b(:,1)), reshape(b(:,2),[],10)];

thank you for your reply. It works.
