In python, how do you generate a distance matrix H where in each entry hij, the distance between row i and row j are stored, distance is computed by the inner product <x,y>C := xTCy, where the matrix C is a 3x3 matrix: [3 1 6 1 2 1 6 1 27]. The dataset is a 26x5 matrix and I need to find the distance using the above inner product between each row - I should end up with a 26x26 distance matrix H, where each diagonal entry (i=j) is 0.
