Hi all,
I want to vectorize a matrix H. However the matrix H is symetric in the off-diagonal entries. The off diagonal entries on the to disired vector have the value of 2*H(ij).
imagine H as:
H = 1 6 7 8 9 6 2 10 11 12 7 10 3 13 14 8 11 13 4 15 9 12 14 15 5
than, the to desired vector has the following form. if H is nxn matrix. the vector should have dimensions n(n+1)/2 with the off-diagonal vectors 2*H(ij) like
1 2*6 2*7 2*8 2*9 2*10 2*11 2*12 3 2*13 2*14 4 2*15 5
What is the best way to solve this problem?
