Functions

func TorgersonScaling

func TorgersonScaling(dst *mat.Dense, eigdst []float64, dis mat.Symmetric) (k int, eig []float64)

TorgersonScaling converts a dissimilarity matrix to a matrix containing Euclidean coordinates. TorgersonScaling places the coordinates in dst and returns it and the number of positive Eigenvalues if successful. If the scaling is not successful, dst will be empty upon return. When the scaling is successful, dst will be resized to k columns wide. Eigenvalues will be copied into eigdst and returned as eig if it is provided.

TorgersonScaling will panic if dst is not empty.
