Before Change

    dT_dc_row = utils.reverse(left_vector)
    dT_dc_col[0] = dT_dc_row[0]
    res = res + toeplitz_matmul(dT_dc_col, dT_dc_row, utils.reverse(right_vector))
    res[0] -= left_vector.dot(right_vector)

    return res

After Change

    Returns:
        - vector m - a vector so that the ith element is the result of \sum_j(u[j]*(dT/dc_i)*v[j])

    dT_dc_col = torch.zeros(m)
