singlelinkage

This package provide a function to perform Single Linkage algorithm on a pairwise distance matrix.

$$\begin{bmatrix} A & B & C & D & E\cr 0 & 7.40 & 7.56 & 5.01 & 12.43 \cr 7.40 & 0 & 8.62 & 6.03 & 6.55 \cr 7.56 & 8.62 & 0 & 12.46 & 4.66 \cr 5.01 & 6.03 & 12.46 & 0 & 9.28 \cr 12.43 & 6.55 & 4.66 & 9.28 & 0 \cr \end{bmatrix}$$

func MatrixLinkage(matrix [][]float64, colname []string) (result string)

The MatrixLinkage function is feeded with a [][]float64 matrix and a []string collecting column names {"A", "B", "C", "D", "E"}

The result is a string in Newick format

((C:4.66,E:4.66):1.89,((A:5.01,D:5.01):1.02,B:6.03):0.52);
