My manual copies of rows code works. but im trying to generalise it into a working algorithm. How do i generalise this?
n = 12
m = n(n-1)/2;
n = 64^2;
S = zeros(m,n);
SFull = zeros(2*m,n);
SFull(1:11,:) = S(1:11,:);

Hi,
To generalize your code into a working algorithm, you can use a loop to iterate over each row of your input matrix, and then copy the row to the output matrix if it meets the desired criteria.
Inside the loop, to copy the matrix ‘A’ row into ‘B’ matrix, use the following line of code:
B = [B; A(i,:)];
