Finding the coordinates of points from distance matrix
The answers based on angles are cumbersome to implement and can’t be easily generalized to data in higher dimensions. A better approach is that mentioned in my and WimC’s answers here: given the distance matrix D(i, j), define M(i, j) = 0.5*(D(1, j)^2 + D(i, 1)^2 – D(i, j)^2) which should be a positive semi-definite … Read more
