WebFeb 26, 2024 · The entry C[0, 0] shows how moving the mass in $(0, 0)$ to the point $(0, 1)$ incurs in a cost of 1. At the other end of the row, the entry C[0, 4] contains the cost for moving the point in $(0, 0)$ to the point in $(4, 1)$. This is the largest cost in the matrix: \[(4 - 0)^2 + (1 - 0)^2 = 17\] since we are using the squared $\ell^2$-norm for the distance matrix.
